Preheat the oven to 425 F. Place the pita on the baking sheet and toast for 2 minutes. Put on your oven mitts to take the baking sheet out of the oven. Use the tongs to flip the pita over. Put the pita back in the oven and cook for 2 more minutes. Use the mitts to take the baking sheet out of the oven and place it on the counter to let the pita cool.
Scoop 2 tablespoons of tomato sauce onto the pita and spread it around with the spoon, leaving a little room around the edges for the crust. Pinch a little bit of Italian herbs between your fingers and sprinkle over the sauce.
Scoop 1 tablespoon of black beans and sprinkle them on the pizza.
Scoop 1 tablespoon of corn and sprinkle it on the pizza.
Scoop 1 tablespoon sliced olives and sprinkle it on the pizza.
Arrange 4 or 5 pieces of broccoli on the pizza.
Arrange pieces of 2 cut up tomatoes on the pizza.
Sprinkle 3 tablespoons of cheese over the top.
Put the pizza back in the oven and cook for 9 minutes. Use your oven mitts to take the pizza out when it is done and let it cool a little before you cut it into four pieces.
