mexican-casserole-recipe2This Mexican casserole recipe is a cheesy flavorful dish.

The mild flavors of green chiles combined with caramelized onions, garlic, ground beef and several Mexican spices make this quiche-like dish quite heavenly. This is a dish that can be served for breakfast, lunch or dinner.

I brought this to a bunko party, cut it up into nice appetizer size pieces and everyone loved it.

Left-overs heat up nicely in the oven.
