  • 12 Siete Cassava Tortillas or tortillas of choice
  • 2 pounds skirt steak trimmed of fat and tendons
  • 1 medium red bell pepper sliced into 1/2" strips
  • 1 medium yellow bell pepper sliced into 1/2" strips
  • 1 medium green bell pepper sliced into 1/2" strips
  • 1 large white onions sliced into 1/2" strips
  • 1/2 bunch Fresh cilantro
  • 2 limes quartered
  • 1 tbsp avocado oil
  • 1 tsp ground black pepper
  • 1/2 tsp Sea Salt


  • 1/3 cup tamari
  • 1/2 cup avocado oil
  • 1/3 cup fresh lime juice about 4 limes
  • 2 tbsp Coconut Sugar
  • 2 tsp Minced Garlic
  • 1.5 tsp cumin
  • 1.5 tsp Chili Powder
  • 1 tsp smoked paprika
  • 1 tsp dried orgegano

Optional, for serving

  • sliced avocado
  • salsa
  • Sour Cream or greek yogurt


  • In a large bowl/baking dish, whisk together all marinade ingredients until combined.
  • Place skirt steak in marinade dish, flipping over a couple times until well-coated in marinade mixture. Cover and place in fridge to marinate for 4 hours to overnight.
  • When skirt steak has finished marinating and ready to cook, remove from marinade (discard marinade) and pat steak dry with a paper towel.
  • Next, heat grill to high (~600℉—700℉).
  • Once heated, place skirt steak onto grill. Cover with grill lid and let steak sear/cook for ~5 minutes on each side until reaching internal temperature of ~170℉ (for medium cooked), or adjust time until cooked to desired level.
  • Remove steak from grill (but don’t turn grill off) and let skirt steak rest on a plate or cutting board for ~5–10 minutes, prior to cutting so as to retain moisture and flavor.
  • While the meat rests, place a large cast-iron skillet on still heated grill — once skillet has heated up, add oil and veggies. Cook for ~10 minutes, or until tender, but firm, and lightly charred.
  • While the veggies are cooking, also place tortillas straight onto the grill and lightly char/heat them on each side (~1-2 minutes per side). Then, set tortillas aside.
  • Once rested, slice steak against the grain into 1/4” thick strips (drizzle any juices on top of cut strips for added flavor and moisture.
  • When ready to eat, assemble fajitas by placing veggies and steak strips onto tortillas, top with cilantro, squeeze of lime, and any optional ingredients.
  • Serve, store, and enjoy!
