Preheat your oven to 400ºF. Optional to use a pizza stone here – makes an even crispier crust!
In a mixing bowl, combine the flour, yogurt, baking powder and salt. Mix to form a shaggy dough.
Dump the dough onto a flour surface and knead for 2 - 3 minutes until you have a smooth ball.
Flour the surface of your ball as well as your rolling pin, and roll the crust out on your floured surface. Flip the dough over a few times as you're rolling, adding flour to the surface between each flip, to prevent sticking.
Once you've rolled the crust to about 1/8" thick, transfer it to a baking sheet or pizza peel (I prefer the peel & stone!). Poke a few holes in the crust with a fork and bake for 10 minutes.
Remove after 10 minutes and top with sauce, cheese and any other toppings you'd like.
Bake for another 10 minutes, then remove and let cool for 2 -3 minutes before slicing and serving.
Notes
To add even more protein, swap the all purpose flour with whole wheat or white whole wheat. The texture won't be quite as crispy, but you'll have a touch more protein per serving.
