Nutritional values

At least once in autumn, a hearty onion tart should be served! However, it is best to try this fruity and spicy creation several times. The combination of onions, grapes and sheep's cheese, baked on crispy wholemeal dough, covers about one third of the daily requirement of the three important minerals calcium, magnesium and potassium.

Prepare the onion tart with reduced fat and thus also with fewer calories using low-fat sheep's cheese.
