I used left over grilled chicken from the night before and kept adding things until it smelled good.
It turned out way better than I had hoped! This should break my Quesada addiction!
Left over chicken (about 1 1/2 breasts) chopped up
1/2 cup chicken stock
1 jalapeƱo seeded and chopped
1/4 cup onion chopped
1/2 tsp red pepper flakes
1/2 tsp ancho chilli powder
1/4 tsp cayenne pepper
Dump in a pan and bring to a boil. Reduce heat to low and allow to simmer for about an hour. If you want more hear, add more peppers or chilies.
If the stock runs out, or dries up, add a little more in.
