Place chicken into a pot with water, bring to a boil and cook on high for about 10-15 min or until cooked, and shred and set aside.
While chicken is boiling, chop onion and pepper, and melt butter in a saute pan. Saute peppers and onions for about 15 minutes or until caramelized. Add salt and pepper to taste.
Once the chicken is done and peppers and onions are sauteed, place desired number of tortillas in the microwave to warm for about 30 seconds (this makes rolling them much easier).
On warmed tortilla, place chicken, peppers and onions, shredded cheese, and add a bit of Frank's and ranch, to taste. Roll tortilla burrito style and let it sit for a few minutes for all the flavors to meld together.
