Enchilada Casserole

I know this isn't a good picture by a longshot, but this enchilada casserole tastes good. I promise! It is from Nava Atlas's The Vegetarian Family Cookbook. I like to add mushrooms to the bean mixture (really I like to add mushrooms to any dish that they go well in). The spiciness of this dish depends on the kind of salsa you use (you can use mild green chilis instead, too). This is the recipe that taught me to extend my soy cheese by melting it into some soy milk and thickening the mixture up with a bit of flour. I have used that trick many times, since it is so hard to get soy cheese to melt well in the oven if you aren't cooking at a very high temperature.
