Fresh Tomato Tart

1 pie crust (if you are buying I like Kroger brand)
8oz mozzarella, shredded
1/2 cup fresh grated or shaved Parmesan
3 T chopped fresh basil, plus more for garnish
4-6 garden tomatoes, sliced
1/4 red onion, sliced really thin
1/2 tsp salt
1/4 tsp fresh ground pepper
1/4 cup olive oil
Preheat oven 400. Bake pie crust in a pie plate for 10-15 mins. Remove from oven and add 2/3 of the mozzarella. Sprinkle with basil. Add layer of tomatoes and onions, seasoning well throughout with salt and pepper. Drizzle with olive oil. Add remaining mozzarella and Parmesan. Bake 25 minutes. Remove from oven and let stand at least 15 minutes. Garnish with more basil.
This is so fresh and delicious! Great vegetarian dinner on a summer night, or serve with a steak from the grill!
