Very kid friendly! This is an easy after school snack or quick lunch or supper when you’re on the run – just add a nice green salad. Substitute your favourite cheeses or mix cheeses for the mozzarella if you like – cheddar, Swiss, Provolone, feta, etc.
Preheat the oven to 425 degrees F. Line a large baking sheet with parchment paper for quick clean up.
Place the pita bread onto pizzas onto a large baking sheet. Spread tomato sauce evenly over the pitas. Top evenly with ham, mozzarella cheese and Parmesan cheese. Season the pizza with salt and pepper, and the dried Greek oregano if using. Drizzle with a little olive oil. Bake until cheese is golden and bubbly, about 10 to 15 minutes. Cut into quarters and serve.
