“This is absolutely delicious,” raves one Allrecipes community member. “I made it once exactly as is and the kids wanted it again the next day, so I had to substitute corn instead of chili beans. That was also delicious.”

“Very tasty and flavorful,” according to another reviewer. “We added taco seasoning and a 6-ounce can of chopped green chiles to the meat/bean mixture.”

“I’ve made it twice,” says Dean Gapp. “Once with ground beef and the other with shredded chicken. Great easy dish! Endless possibilities for modifications.”
