Preheat oven to 375 degrees F (190 degrees C)
Add the Ham (1 cup), the chopped Yellow Onion (1), Red Bell Pepper (1/2), Cheddar Cheese (1 cup) and Tomato Sauce (12 ounce) into a mixing bowl. Mix everything all together. Set aside while you prepare the dough.
Into a big bowl, add Water (1 cup), Granulated Sugar (2 tablespoon), and Instant Dry Yeast (1 3/4 teaspoon). Stir everything together for 2 minutes until the yeast foams up.
Add the Olive Oil (2 tablespoon), All-Purpose Flour (3 cup) and Salt (1 tablespoon). Mix well into a dough. Turn the dough into a floured surface, and kneed until it is smooth and elastic.
Shape the dough into a sausage shape, and cut into 6 even pieces. Roll each piece into a circular shape.
Once you have the flat circular dough, put the pizza mixture into on half of the dough, fold the dough over and pinch together the edges. Using a skewer, poke a couple of steam vents by the side of the pocket.
Put the all the pieces on a baking tray, and bake under 375 degrees F (190 degrees C) for about 20 minutes.
After baking, let the pockets down for 5 minutes, and Serve!
