Thinly slice the 1 pound boneless skinless chicken thighs and mix well with 1 tbsp of the 1 1/2 tablespoons olive oil and 1 1/2 tablespoons Taco seasoning.
Heat a large skillet over medium heat. Drizzle with remaining 1/2 tbsp of oil and add the chicken in a single layer. Cook for 5 minutes, stirring occasionally.
Stir in the 1 medium onion (sliced), 1 red bell pepper (sliced), and 1 orange bell pepper and continue to cook, stirring often, for 5-6 minutes.
Add the 4 cloves garlic and 1/4 cup low-sodium chicken broth and stir through the bottom of the pan. Sprinkle with the 2/3 cup shredded mozzarella cheese and set the lid on.
Keep on low heat for 2-3 minutes more, with the lid on, to make sure the cheese melts. Garnish with fresh cilantro and lime wedges, and serve over cooked rice, if desired.
Notes
Have your veggies and garlic prepped before you start - this one cooks quickly.
Slice the chicken nice and thin so it cooks fast and soaks up all the flavor.
Let the chicken sit in the pan for a bit before stirring to get that golden crust.
Keep your peppers and onions the same size so they cook evenly.
Pour in the broth to deglaze the pan and grab all those yummy bits.
Cover the skillet so the cheese gets perfectly melty.
