I already know what you're thinking... "lasagna isn't Mexican" or "is he out of his Tex-Mex mind?" While I've been accused of being mindless on occasion, I'm definitely not out of my mind this time.
Like Garfield the Cat, I'm a big fan of lasagna... mostly the Italian kind. I have an Italian lasagna recipe that I got from my dad that I used to make often when my children were younger, but for reasons I really haven't been able to describe I've made it only once in the past 20 years or so. That one time was for a very somber occasion, the passing of my younger brother just a few months ago, where I volunteered a turn at cooking dinner and that was what the family requested. I'll get around to making that one someday and posting it here, but not today.
Today, we have a southwestern style lasagna named after our neighbors to the south. Rightly it should be called a Tex-Mex dish that's more along the lines of multi-layered quesadillas or even stacked flat enchiladas, but I didn't name it... I just tried it, so that's what we'll keep calling it here.
I did make a couple of changes to this recipe from the original. First, the listed recipe called for a can of diced tomatoes and a can of green chiles. I replaced those with two cans of Ro*Tel diced tomatoes and chiles, a staple among Tex-Mex cooks here in Texas and surrounding states. I also played around with the serving sizes; it called for 12 servings from a 9 x 13 casserole dish, but my experience has been that 8 servings from one is more often found, especially here in Texas where servings are typically larger (although in this case you'd probably want to cut them down by half for smaller children).
