Zucchini Frittatawith Onion and Parmesan
Italian baked frittata with sautéed zucchini and onion, beaten eggs, and Parmesan, served in firm yet moist slices.

The frittata cooks the vegetables before adding the eggs and finishes in the oven, which distinguishes it from a folded omelet. The zucchini releases some of its water in the skillet; then, eggs and Parmesan form a round, cohesive, and still moist dish.
