  • 1 1/2 tablespoons avocado oil, divided
  • 4 medium bell peppers, julienned (600 grams)
  • 1/2 onion, sliced (200 grams)
  • 2 heaping cups mushrooms, sliced (200 grams/12 mushrooms)
  • 1 tablespoon taco seasoning (divided)
  • 1 pound shrimp, peeled and deveined
  • 1 tablespoon lime juice
  • optional for serving: cauliflower rice, chopped romaine, diced tomatoes, avocado, fresh cilantro, limes


  • In a large skillet or cast iron over medium heat, add 1 tablespoon avocado oil and let it get hot. Add onion and sauté for 5-7 minutes, stirring occasionally, until softened and slightly browned. Add peppers and sauté for another 5 minutes, stirring occasionally. Add 1/2 tablespoon taco seasoning and mix to combine.
  • Add in mushrooms and sauté for another 2-3 minutes. Push veggies to one side of the pan to make room for the shrimp. Add remaining 1/2 tablespoon avocado oil, shrimp, and the remaining taco seasoning. Cook for 3-5 minutes, flipping halfway through until pink and cooked through. I like to add half the taco seasoning to one side of the shrinmp, flip, and then add the rest. Mix everything together, add 1 tablespoon lime juice, and mix again. Top with fresh cilantro and serve with sides of your choice.


To make shrimp fajita bowls, fill a bowl with chopped lettuce (or greens of choice), add in your shrimp fajitas, top it with some of the toppings above, and using salsa as a dressing. This way works great for leftovers too (if you have any!).
