Mushroom Lasagna With Bechamel Sauce ~This dairy and mushroom lasagna is meatless so all Vegetarian Readers can feel free to read on! Being Italian I have made lasagna for years. About 45 years. Meals I can make the night before and then throw in the oven before a dance recital, game, or running the kids to an appointment have become very popular in my house. The fridge does a great job of marrying all the flavors together and the deliciousness of the flavor is a great reward! All the cleanup is done the night before leaving you with just one dish and a spatula to wash after dinner. This is an awesome go to meal when you find yourself smack in the middle of a busy week!
