Small Onion Quiches

Preparation:

Preparation: Slice the onions very thin and stew them in a non-stick pan, covered, with 4 tablespoons of oil, for 10 minutes. Pour in the sugar, vinegar, salt, raise the heat and let them caramelize for 5-6 minutes. Cut from the pizza dough 4 discs of 12 cm and 4 long thin strips for decoration. Line the bottom and edges of four tartlet moulds, prick the bottom and form a border by folding over the excess pastry. Fill them with onions. Beat the cream with the egg and a little chopped thyme. Season with salt and pour over the onions. Put a slice of goat cheese on each cake and decorate with the pastry. Bake in a hot oven at 200 degrees for 20 minutes. Sprinkle with the hazelnuts, decorate with the spinach leaves and serve immediately.
