Roll out the other pizza crust. Using a cookie cutter, cut out 7 to 8 circles (depending on how big your cookie cutter is). You can use the saved edges for this as well. Slice each circle in half, creating semicircles. Press each semicircle into the edge of the pizza. Continue until all the the semicircles are pressed into the pizza. Using your fingers, pinch the edges of the half circles to create little bowls.
