This is my current go-to when I don't feel like cooking.
It is somewhat healthy, inexpensive, but more of all... easy.
1 bag of 365 brand organic blue corn tortilla chips
1 bag 365 shredded cheddar- to taste, i only use about 1/2 cup
1 can 365 black beans
Makes 2 batches-- use half of everything, then make again
everything else is optional! You can leave it at the above if you want.
Melt at 375 for 6-10 minutes
Optional... jalepeno, sour cream, salsa, avocado, onion, anything!
