In a large bowl, combine your chopped chicken, spinach, pesto, chili flake, and parmesan cheese. Mix well with your hands and set aside in the fridge.
In a bowl mix together flour, greek yogurt, baking powder, and salt. Mix with a wooden spoon and then tip onto a lightly floured work surface and knead until dough is smooth.
Divide the dough into 8 equal balls.
Flatten your balls of dough, adding about 3 tbsp of pesto mix into the middle. Using your hands, fold the sizes over to seal in the chicken. Flatted out the ball to make a burger or hockey puck shape.
Place a pan over medium low heat and place the pizza buns onto the pan. Cook each side for around 7-10 minutes per side. Make sure temperature isn’t too high or they will burn. Take your time with this process.
After about 15-20 minutes on the pan, remove and ENJOY!
