Lots of fun to make and especially eat! I am a vegetarian, so I have substituted vegetarian "chicken" in this recipe and it was fabulous, but if you are a meat-eater you can use the same amount of real chicken instead with the same delicious outcome. I also used a combination of mozzarella and cheddar cheeses because Mexican cheeses aren't available to me here in England but if you would prefer monterey jack or other Mexican cheeses go right ahead and use them instead. These were soooooooo good. Enjoy!
