Mexican Lasagna

I love using these cookbooks for menu ideas and often don't even use the recipes. The backs of the books always contain several weeks worth of daily menus, and I always use one of the books (I have four) when writing my grocery lists. When I do use the recipes, they are consistently good. They almost always need additional salt (this one was no exception). I usually make substitutions with regular cheese and 1% milk if such things are called for. I don't think it adds that much to the calories. The Mexican Lasagna was a hit with my mother (who is visiting), and my husband said he would eat it again. It's made with corn tortillas and beans, rather than pasta and meat, so it would be a good vegetarian meal.
