This keto-approved take on fajitas is a super satisfying low-carb meal. The chicken shreds off the bone easily, while the veggies have a slight crunch and the broth is light and flavorful. It feels indulgent, but you’re not breaking any rules.
Set Instant Pot to “sauté” and allow it to preheat for 3 minutes. Heat 2 teaspoons of the oil until hot. Add bell pepper, onion, and garlic; stir and arrange in an even layer. Cook, undisturbed, until lightly browned around the edges, about 3 minutes. Stir, and continue to cook until tender and golden, 3 to 5 minutes. Transfer onion mixture to a plate.
Stir together salt, chili powder, cumin, and pepper; sprinkle most of the spice mixture evenly on the meaty side of chicken breasts. Add remaining 1 teaspoon oil to pot. Place chicken, spice side down, in hot oil, and sear 3 minutes. Sprinkle bone side of chicken with remaining spice mix; flip. Add stock; cover and press cancel. Set cooker to high pressure for 10 minutes.
Carefully release pressure and remove lid. Press “cancel”. Transfer chicken to a platter; shred chicken and discard bones. Place shredded chicken and onion mixture in hot liquid. Serve fajita mixture over cauliflower rice; top with tomatoes, cheese, sour cream, avocado, and hot sauce.
