Preheat oven to 375°F and spray two 12-cup muffin tins with olive oil.
In a bowl, whisk flour, baking powder, and salt.
Add Greek yogurt and mix until crumbly dough forms.
Transfer dough to a floured surface and knead about 15 times until tacky but not sticky.
Divide into 16 equal balls.
Press each ball into muffin cups, slightly up the sides.
Bake for 15 minutes.
Remove and press centers to form a well.
Add sauce, cheese, and turkey pepperoni.
Bake another 3 minutes until cheese melts.
Cool slightly, then remove and serve your Turkey Pepperoni Pizza Bites warm.
