Clean the broccoli, cut into florets and cook in salted water until cooked. Clean the remaining vegetables, cut into slices and fry one after the other in the oil. Dice the ham and sauté briefly. Layer everything in a baking dish. Whisk the eggs, mix with cream, season and pour over the vegetables, sprinkle with cheese and bake at 160 ° C for about 20-30 minutes, until the egg mixture has set and the cheese has the desired degree of browning.
