Mel's Favorite Foods: Mexican Lasagna

I got this recipe from the Costco cookbook my sister got me a few years ago.  We both love this one too!  I made his with beef, & beef chorizo & mine was with veggie beef.  He also had spicier salsa in his and his black beans had jalapenos in them.  This recipe is supposed to have onions and peppers in it, but since it already has salsa in it, I traded those ingredients for corn, black beans, and fire roasted garlic tomatoes.  It's supposed to have sour cream in it, but Mel hates sour cream. I forgot to add it to mine until it was already in the oven, so I just put it on top as you see in the photo.
