Mexican Pizza

One 12- to 14-inch good-quality pizza crust
1 cup (about half of a 16-ounce can) spicy vegetarian refried beans,
      thinned with a small amount of water
1 cup mild or medium-hot salsa
1 to 1 1/2 cups grated vegan cheddar or Monterey Jack cheese
1/2 cup frozen corn kernels, thawed
1 to 2 scallions, sliced, optional



Preheat the oven to 425 degrees. Place the crust on a pan. Spread it with the refried beans, then the salsa. Sprinkle with the cheese and corn kernels. Bake until the cheese is bubbly, about 8 to 10 minutes. Remove from the oven, let stand for 2 to 3 minutes, and cut into 4 or 6 wedges to serve.
