Mix the seasonings together.
Add the chicken, peppers, and lime juice, stir. If freezing, place everything in a freezer bag and seal. Place in freezer.
Allow to marinate 30 minutes. I made the pico while I was waiting.
If cooking in a skillet, add chicken and the sauce to skillet that is on medium heat. If cooking in the crockpot, place in CP and cook on low 5-7 hours or high 3-4 hours.
As it cooks, stir. I broke up the chicken a little as it cooked. Cook until the chicken is cooked through.
If you are cooking your shells, get everything ready and fry your shells. If your fat gets too hot, temporarily remove the skillet from the heat.
Once your tortilla has cooked for about a minute, flip it over, add meat and pico to one side and fold over. Be careful. Drain on paper towels.
Serve with desired sides.
