I have made a Layered Chicken and Black Bean Enchilada casserole before. It was pretty good, I did change the recipe a tad just to reflect my spice taste buds (I like everything extremely spicy). That site also has a video showing how to make it, which you don’t really need to follow if you have culinary skills, but I link to it because of the other recipe links they have on that page. Especially the Red Enchilada Sauce recipe is what made that casserole an instant win. I also like that it lasts for a while, is fast and easy to make and easy to reheat!
I make mexican lasagna – pretty much the same as @Allie‘s enchilasagna:
Layer in a casserole dish: – black beans – grated cheese – corn tortillas, cut into 1” wide strips – sour cream – salsa
Repeat layers 2 1/2 times, ending with a grated cheese layer on top. Bake @ 350 for 20–30 minutes – until it’s all hot and bubbly – and then top with guacamole. So yummy!
