Best Whole30 + Keto Taco Shell Substitute

Rather than using flour or corn tortillas, I’ve swapped them out for butter lettuce leaves. It’s my favorite healthy substitute. Cabbage or romaine leaves work too, but butter lettuce is by far my favorite.

The leaves are sturdy yet delicate, wide, and the perfect vessel for a healthy taco.

Add on a few more jalapenos and a big squeeze of lime and your taco dreams will come true.

If your diet allows, feel free to use flour, corn, or Siete tortillas (as pictured above, my favorite grain free tortilla).

Ingredients
 
 

Spicy Coleslaw

  • 1/2 cup mayonnaise
  • 2 tablespoons lime juice from about 1 juicy lime
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 6 cups shredded green cabbage
  • 1/2 cup cilantro chopped
  • 1/2 cup green onions chopped
  • 1 jalapeno ribs and seeds removed, finely diced (or more for spicier)

Taco

  • 4 6-ounce mahi mahi filets, cut into 3" x 1" strips
  • 2 tablespoons avocado oil
  • salt + pepper
  • butter lettuce leaves for taco shell or siete tortillas for paleo/GF
  • sliced avocado optional

Instructions
 

Spicy Coleslaw

  • In a large bowl, make the dressing in the bottom by combining the mayo, lime juice, salt and pepper. Whisk to combine. Add in the cabbage, cilantro, green onions + jalapeno. Toss to combine.

Taco

  • Heat your cast iron skillet over medium heat for 5 minutes.
  • Season your cut up mahi mahi generously with salt + pepper.
  • When the cast iron skillet is warm, add in the avocado oil. Working in batches so there the pan doesn't get too crowded, add in the mahi mahi, and sear for 4-6 minutes without touching it until crispy and golden brown. Flip, and cook an additional 1-2 minutes. Remove and rest on a plate. Repeat with the remaining mahi mahi if necessary.

Assemble

  • Place mahi mahi on each butter lettuce. Top with avocado slices and the spicy coleslaw. Enjoy!
