Tortilla a la paisana is a country-style variety of a Spanish omelet. It's made with the same ingredients (eggs, potatoes, salt, oil, and sometimes onions) with the addition of vegetables and jamón serrano. The vegetables used in tortilla a la paisana are usually bell peppers, peas, asparagus, and zucchinis.

The ingredients are mixed together and fried as an omelet, which is later served sliced into smaller portions. The dish can be served warm, at room temperature, or even cold.
