Breakfast, lunch, dinner, dessert, snacks, leftovers...I use it for everything. Preheats in a flash with accuracy and maintains temp. Whether I'm toasting bagels, roasting veggies,  broiling fish, frying bacon, baking cornbread, or just reheating leftovers....anything that fits in this wonderfully compact oven, goes into it. Then, it comes out fabulous. I love it!
