In a large bowl, whisk together flour and salt. Make a well in the center and pour in water, yeast and sugar. Let sit until foamy, about 5 minutes. Then, add olive oil and mix ingredients together until a dough forms. Pour dough onto counter and knead about 8-10 minutes. Place dough in a lightly greased bowl, cover and let rise until doubled, about 1 1/2 hours.

Preheat oven to 400 degrees F. Place risen dough on countertop and, using a rolling pin, roll into a very, very thin square (about as thin as the walls of a ravioli). Using a pizza cutter, cut square into strips lengthwise and then cut crosswise so you have about 56 individual 1 1/2-inch squares (or as many as you end up making).

Put about 1/2 tsp pizza sauce on half the squares, and top with the same amount of cheese. Take the plain squares and place them on top of the squares with sauce and cheese and pinch the seams closed. Press fork tines around the edges of the squares to close the seams completely. Place each pocket on a baking stone or parchment paper-lined baking sheet and bake for about 10-15 minutes or until lightly brown on the edges (I had to take mine out before they were very brown at all because the cheese and sauce was exploding out of the sides -- oops). Serve immediately.
