i'm not one to cook exactly according to a recipe, but i use recipes a lot for ideas and guidelines on the proportion of ingredients, temperature and how long to cook. so what i did was google vegetarian enchilada casserole crockpot recipe, and vegetarian lasagna crockpot recipe. these are the recipes i'm using as guidelines (and to make my shopping list):
http://www.food.com/recipe/crock-pot-vegetarian-lasagna-173879 but i'm not using mushrooms because i hate them, and adding zucchini because i love it
http://www.cdkitchen.com/recipes/recs/48/Vegetarian_Enchilada_Casserole57470.shtml but i'm adding cheese, because who would want to eat this without cheese?! also, i would normally probably not use salsa, because that sounds weird to me - i'd probably buy cans of enchilada sauce. however, i have a big jar of salsa that i don't love, that my mom left at my house, that i'm going to use up in this recipe. i might make some rice or something to go with it too, idk.
