Heat your grill to medium-high heat.
Mix together the pesto and pizza sauces.
Coat the metal tray with vegetable oil, and spread out the pizza dough.
Cover the pizza with the sauce, and layer on the spinach, mushrooms, and tomato slices.
Top with the cheese, and place on the grill.
Cook until the bottom of the pizza is browned and the cheese has melted. Remove from the metal pan and serve.
