I make this recipe all the time. I double it, and use 2 lbs of ground turkey instead of beef. Also, instead of doubling to 4 cans of kidney beans, I use any combination of 4: canned corn, garbanzo beans, black beans, navy beans, etc. I also use canned diced tomatoes instead of whole tomatoes. I love this recipe and make it with cornbread often. I don't even put cheese on it and it's still delicious.
