I went to Costco a few months ago and sampled a yummy Mexican mouthful. Super tasty, super easy, super fun. They only put the salsa, chicken and cheese together and served it with tortilla chips. I added a few extra ingredients and served it in a tortilla (burrito style). In true "Pam Style," I don't really measure except when baking. So just add these ingredients to suit your personal taste.
1 jar Costco organic salsa (you can use another kind)
2 cans Costco chicken pieces (you could use chicken you cooked and chopped yourself)
Grated cheese to taste
Put all ingredients into a pot and heat until warmed. Serve in a tortilla or with chips.
My friend said she may try adding corn kernels too.
