Vegetable Frittata

"A frittata is an Italian omelet to which the add-ins (potatoes, ham, cheese, veggies, rice, what have you) are beaten directly into the eggs. Generally it’s cooked first on the stovetop, then finished under the broiler. Some people cook a frittata entirely on the stovetop, flipping it during the cooking process instead of transferring the unflipped frittata to the broiler. Frittatas are great warm, or at room temperature, happily hanging out for a couple of hours before being cut up and served. Ideal for brunch, they are a subtle way of saying “I’m not making individual omelets for all of you.” A good potluck notion and, when cut into small squares, a lovely hors d’oeuvre...."
