I liked this with the tomato sauce, but you could skip it and put the mozzarella on the bottom if you like, to emphasize the flavors of the veggies more.
1 14-inch pizza crust
3/4 cup tomato sauce (optional)
2 cups Grilled Summer Squash and Onions
2-3 oz crumbled or diced blue cheese (Gorgonzola or local blue of your choice)
2-3 oz shredded mozzarella
Preheat the oven to 450 degrees. Lightly paint the pizza crust with olive oil.
Spread the sauce over the crust, then top with the grilled vegetables. Sprinkle with blue cheese and mozzarella, then bake for 15-18 minutes, until the crust is done and the cheese begins to brown.
