Wonderful comfort food! One of my family's favorites. Great casserole to "make and take". You can make it as spicy as you want. My mother made this with ground beef, I sometimes make it with leftover cooked, diced chicken for a lower fat alternative. Reminds me of my mom when I make it! You can serve it with Pico, sour cream or cilantro. TIP: I use a dutch oven - that way I don't have to transfer it to a casserole dish - thus saving myself a dish to wash!
