This vegetable filled frittata is a wonderful way to start spring by celebrating asparagus, which is now in season and tastier than ever. It will satisfy even the hungriest of appetites and is a delicious, simple, and cost friendly meal. It is a perfect dinner for two on Meatless Monday or a nice addition to a brunch for 4 or more. Sautéed red pepper, zucchini, or onion would make fantastic additions to this dish and if asparagus just isn't your favorite, steamed broccoli would be a good substitution.
