Tortilla de cipollo

Frittata di cipolle is a traditional frittata dish prepared with onions. The dish is made with a combination of beaten eggs, olive oil, onions, salt, and pepper. The onions are cut into thin slices and cooked in olive oil over low heat until soft and golden. The eggs are beaten, seasoned with salt and pepper, then poured over the onions. The dish is cooked until it becomes golden brown and set on one side. It's then turned on the other side and the process is repeated until the frittata is done and ready to be enjoyed.
