Preheat the oven to 375 degrees F. Line a baking sheet with parchment paper
PREPARE THE PIZZA DOUGH:
In a large bowl, using a wooden spoon, stir together the yogurt and flour until combined. With your hands, knead the dough in the bowl until smooth, about 2 minutes, adding additional flour, 1 tablespoon at a time, if dough is sticky.
Place a large piece of parchment paper on a work surface and lightly sprinkle with flour; place the dough on the paper. With a knife, cut the dough into 4 equal pieces. Using a lightly floured rolling pin, roll each piece of dough into a 6 to 7-inch oval. Place the ovals of pizza dough onto the prepared baking sheet; bake until the dough is beginning to turn lightly golden, about 18 minutes.
ADD THE TOPPINGS (these... or whatever toppings you want):
Remove the crusts from the oven and top each with 1/4 cup of the sauce, 3 tablespoons of mozzarella and 5 slices of pepperoni. Return the pizzas to the oven and bake until the crust is cooked through and the cheese is melted, about 5 minutes longer. Sprinkle each pizza with 1 tablespoon Parmesan, 1/2 tablespoon basil and a pinch of red pepper flakes. Cut and serve. One pizza per serving.
If you just want to make the crust and add your own toppings, the CRUST ONLY counts as 3 blue WW points, 4 green WW points and 3 purple WW points.
