This is a fun spin on both Lasagna and Tacos. I was inspired by something my mother used to make when I was a little girl (she called it Mexican Casserole) though hers was made with flour tortillas and modeled a bit more after enchiladas than tacos. I needed gluten free, though, so though I'd try it with fried corn tortillas. Ours turned out nothing like my mom's (probably has something to do with the fact I never actually asked her for the recipe) but it was a big hit here!
It takes about an hour from start to finish and I love it because I have just enough time to do all the dishes before pulling it out of the oven and setting the table. It's simple, easy cleanup, and all the food is in one dish. Garnish with sour cream and hot sauce.
