So you want to eat tasty spicy food tonight, eh?. Not exactly authentic Mexican. Contains chicken, not beef, which, as I read above, does mean they are by definition, not actually fajitas, but I couldn't think of a better spot to put this. This makes enough for 4 or 5 people. With the suggested levels of spicy ingredients, it is sufficient to make most people cry. Adjust as necessary.
Mix all the above stuff (except the chicken) together, in a casserole dish. Understand that all measurements above are approximate. Add the chicken and get it coated nicely. Cook at 400 Fahrenheit for about an hour. When done, cut into bite-size pieces.
Chop the vegetables as you like them and stir fry them in the other ingredients. Should take 5-7 minutes to reach a tasty consistency.
Serve the above two dishes with warmed flour tortillas, shredded cheddar cheese, chopped romaine lettuce, tomatoes, and salsa. Rice is a nice addition, too.
