Fantasticly Yummy and Rustic Zucchini Tart

Heat 3 tbsp. of unsalted butter and stir in 1 tsp. of basil and then 2 cups of sliced onions and garlic. Sauté for 5 minutes. Add 2 ½ cups of zucchini and sauté until liquid is gone - 5 minutes. Spread 1 cup of mozzarella over an already made and baked pastry shell and top with zucchini mixture. Bake in the oven for a further 5-10 minutes. Very delicious. Slice up and serve.
