Preheat oven to 350 degrees F (175 degrees C). Place pizza crust on baking sheet. In a small bowl، mix together olive oil and sesame oil. Brush onto pre-baked pizza crust، covering entire surface. Stack the spinach leaves، then cut lengthwise into 12 inch strips; scatter evenly over crust. Cover pizza with shredded mozzarella، and top with sliced mushrooms. Bake in preheated oven for 8 to 10 minutes، or until cheese is melted and edges are crisp.
