Spinach and Mushroom Pizza

1 (12-inch) pre-baked pizza crust
1 to 2 tbsp. olive oil
1 c. fresh spinach, rinsed and dried
8 oz. shredded mozzarella cheese
1 c. sliced fresh mushrooms
2 to 3 garlic cloves, minced
~ 1 tsp. dried basil
Ground pepper, to taste

Preheat oven to 350°F. Place pizza crust on baking sheet. Brush olive oil onto pre-baked pizza crust, covering entire surface. Sprinkle minced garlic evenly over crust. Stack spinach leaves, then cut lengthwise into 1/2-inch strips; scatter evenly over crust. Cover pizza with shredded mozzarella, and top with sliced mushrooms. Sprinkle dried basil over the top and season with pepper. Bake 8 to 10 minutes, or until cheese is melted and edges are crisp.
