Preheat the oven to 425 degrees.
Make the dough by mixing the flour, yogurt, baking powder and salt until dough
forms. You'll want to knead in a ball about 15 times. If it's sticky add flour to your hands.
Sprinkle a flat surface with flour. Roll your dough out into. rectangle (big enough to cut 6 slices vertically and one in the middle horizontally) Make those slices to create 12 "bites".
Add 1 pepperoni slice and 1/8 cup cheese to each "bite". Keep them to one side of the rectangle so you can fold the other half over. Spray the perimeter of 1/2 with butter spray. Fold the other half on top of it. Use a form to go all the way around and press to close. Spray the tops with cooking spray.
Bake them for 15-18 minutes or until golden brown. Serve with pizza sauce for dipping.
