Preheat oven to 375℉. Line a large rimmed baking sheet with parchment paper.
In a mini food processor, add in your cottage cheese and pulse until smooth.
In a large bowl, add in the cottage cheese, flour, baking powder, salt, sun dried tomatoes, mozzarella, basil, olives and mix together until combined. Use your hands to form the dough into a thick log (6 inches long). Divide the dough into 6 equal pieces. Shape the pieces into flatter circles and poke a hole in the middle with your finger. Place onto your pan and brush them with egg wash. Bake for 22-25 minutes or until golden brown on top. Transfer to wire rack to let cool completely.
