In a large skillet over medium-high heat, add two tablespoons of vegetable oil. Add the chicken to the pan and sear until browned on both sides.
Add one cup of water to the pan and cover until the chicken is cooked through, about 45 minutes. Remove from the pan and shred using forks. Season with salt and pepper.
Preheat the oven to 350°F (175°C). Chop the onions and bell peppers.
Wipe out the skillet used to cook the chicken, then add the remaining two tablespoons of vegetable oil to the pan and bring to medium-high temperature.
Add the onions and bell peppers to the pan and sauté until beginning to soften.
Sprinkle in the chipotle powder, cayenne pepper, garlic powder, and onion powder. Squeeze in the fresh lime juice.
Toss the cooked shredded chicken into the pan with the vegetables. Add a dash of spicy hot sauce and stir well.
Add about a half cup of the chicken and vegetables to the center of a tortilla, then roll up the tortilla. Repeat with the remaining filling and tortillas.
Wipe out the pan used to cook the chicken and vegetables. Spray with some non-stick cooking spray.
Arrange the chicken roll-ups in the pan, then top with about a half cup of the shredded spicy cheese.
Bake the chicken roll-ups for 15 to 20 minutes or until the cheese on top is melted, and the ends of the tortillas are crispy. Serve with sour cream and garnish with parsley. Enjoy!
