Preheat oven to 425 degrees.
Spread a few tablespoons of pizza sauce atop a piece of pita bread. Then layer with Canadian bacon and diced pineapple. Sprinkle cheese on top, then add a few more pieces of Canadian bacon and pineapple.
Place on a cookie sheet (or directly on the oven shelves) and bake for 8-10 minutes, or until cheese is melted and pita reaches desired level of crispness. Remove and use a pizza cutter (or a sharp knife) to cut into slices, and serve immediately.
Since these are so small, I also love making these in the toaster oven!
