When it comes to succulent delicious thin sliced beef, this grilled flank steak is amazing. Much like bavette steak, it’s begging for a hot quick grill and to be sliced and served with tons of chimichurri and toppings.

Trying the Whole30 diet had me locked down on a few simple meals, hundreds of eggs, and pretty much-hating life. Then I remembered that I loved to cook and really started creating recipes that rocked!

This Grilled Flank Steak with fresh Chimichurri over Saffron Cauliflower Rice is my spin on fajitas really taking things up a notch with pineapple marinated steak and saffron-infused ‘rice’. Just what I needed to make the rest of my Whole30 diet fun – and a ton of recipes that were totally amazing!

Can you survive the Whole 30 Diet?

A few months ago, I tested out the Whole30 Diet and swore to myself I wasn’t going to starve to death. We can get into the long and boring answer of why I would be crazy enough to cut anything from my diet, but the reality is, I wanted to try it.

The first few days, as instructed in the book, did suck. But, I really started to wonder just why. I mean, I cook everything anyway, not allowing myself carbs, cheese, and a few sugary drinks shouldn’t really be that hard.

The trick to Whole30 success? Focus on what you CAN have.

Then I realized, it was because I was focusing on the things I couldn’t have. All of the hard ‘NO’s’. I was reading and re-reading the rules as though someone had come down from the mountains with tablets carved of stone and I was sure to muck it up.

Sure enough, this ‘I can’t’ mentality was crushing my creative spirit and leaving me one sulking cuss who was just whining about how hard everything was.

Truth, it’s not hard.

It’s not hard at all.

And seriously, don’t try to google 75 ways to create Whole30 Approved desserts. That’s kind of self-sabotage for the whole thing.

Instead of focusing on all the things you can’t have on Whole 30 and locking down like 3 meals to reuse for 30 days in a row, start to think about all of the flavors you can create, the basics of cooking, how to infuse and mingle flavors to appease your taste buds.

How to incorporate texture to keep everything toothsome. Once that switch flipped in my mind, things got good. Real good. Like, pineapple marinated Grilled Flank Steak with fresh Chimichurri over Saffron Cauliflower Rice good.

At the end of the 30 days, I hadn’t lost a pound, but I did feel great. I was sleeping really well and really enjoyed the way my body felt. I will admit, I was disappointed it wasn’t a miracle weight loss solution, but as a runner, and mountain biker, I realize my body fluctuates pretty evenly from month to month.

Overall thou, the feeling great is a reward all to itself and I ended up using some of the basic principles I learned in many meals since.

Savory grilled flank steak sliced thin over light cauliflower rice and topped with what I call 'magic sauce' aka, chimichurri may be the best healthy meal you have ever tasted. Oh, and it's not at all as complicated as it sounds. Make and impress the fussiest of eaters.


  • 2 lbs Flank Steak
  • Salt and Pepper
  • 1 tbs Cumin
  • 1 tsp Red Pepper Flakes
  • 1/3 cup Coconut Aminos see note
  • 1/2 cup Pineapple Juice

For the Chimichurri

  • 3/4 cup Olive Oil
  • 1 large bunch fresh Parsley
  • 1 tsp Red Pepper flakes
  • 4 cloves Garlic
  • 1/2 Red Onion

For the Saffron Infused Cauliflower

  • 1/2 cup Chicken Stock
  • pinch Saffron
  • 2 cups Cauliflower Rice* frozen, see note
  • 15 oz Fire Roasted Peppers and Onions for combining frozen package


Marinate the Steak

  • Pat the flank steak dry and season with salt and pepper.
  • Mix cumin, red pepper flakes, coconut aminos, and pineapple juice in a large resealable bag. Add the flank steak and marinate in the refrigerator for 4 to 6 hours.

Grill the Steak

  • When ready to grill, grease the grill grates and preheat your grill or light and prep your coals if using charcoal.
  • Remove the steak from the marinade and reserve the marinade.
  • Pat the steak dry and grill to medium rare, flipping once.
  • Allow the steak to rest in foil for 10 minutes before slicing.
  • Meanwhile, in a small saucepan, bring the marinade to a boil. Reduce heat to low and simmer until liquid has reduced by half.

Make the Chimichurri

  • In a blander or food processor, blend the olive oil, parsley, red pepper flakes, garlic cloves, and red onion until your chimichurri has reached your desired texture. Add more or less oil to thicken or thin.

For the saffron infused cauliflower rice

  • Simmer chicken stock in a large skillet with saffron to infuse.
  • Strain into a heat safe jar. Add the cauliflower rice to the skillet and toast.
  • Add the infused chicken stock to pan and toss to coat the cauliflower.
  • Finally, arrange the fire roasted onions and peppers on a platter with the saffron cauliflower rice.
  • Slice the flank steak and arrange over top with a garnish of chimichurri.
  • Spoon the reserved marinade over the top of the steak.
  • Serve family style, allowing everyone to take what they want, with more chimichurri on the table for passing.


This recipe works best if you marinate the steak, then prep the cauliflower rice and chimichurri right before, or while the steak is grilling and resting. 
If you aren’t concerned with Whole 30, you can use Worcestershire Sauce in place of the coconut aminos. 
Rice can be used in place of the cauliflower. If you are making the swap, go with yellow rice. Personally, I love this Vigo brand.

  1. What do you do with the leftover marinade once you’ve reduced it by half and are the fire roasted peppers and onions something you prepared ahead or bought?
    Please answer, really want to try this recipe!!!!

    1. Hey Hey, Drizzle that reduction over the steak when you serve it. Mmmmm. I love adding flavor layers.

      For the fire roasted peppers and onions – these are a great find from Trader Joe’s! They are in the freezer section and on nights when I don’t have 10 minutes to slice and grill my own (another fine option) I toss them in.

      Please let me know if you try this one. I absolutely love this recipe.
