Stir together the warm water, yeast, and sugar in a liquid measuring cup. Let sit for about 5 minutes, or until small bubbles form. Pour into a large bowl.
Add the oil, salt, and about 1 1/2 cups of the flour to the yeast mixture. Whisk or beat until smooth.
Gradually add enough flour to form a soft dough that is slightly sticky, but won't stick to your fingers.
Dump out onto a floured surface and knead for a couple of minutes, or until smooth.
Spray the bowl with cooking spray and place the dough in the bottom. Cover and let rise in a warm place for about an hour, or until doubled. Punch down.
Preheat your oven to 450°. Spray cookie sheets with cooking spray.
Divide the dough into 16 portions. (They should be about 2 ounces each.) Press each portion out into a 4 1/2-5 inch circle on a prepared cookie sheet.
Poke holes in the dough with a fork. Bake at 450° for about 5 minutes.
Remove crusts from the oven and spread each one with about a tablespoon of sauce. Add two olive slices for the eyes. Pull off pieces of the string cheese and lay them across the pizza so they look like mummy wrap.
Turn the oven down to 400° and bake the pizzas for 8-10 more minutes or till crust is golden brown and the cheese is melted.
