Preheat the oven to 400 ℉
Prepare a baking tray by lining it with parchment paper.
Put onions, red and green bell peppers in a food processor and chop it until it is fine. Do not make a paste!
Place the onion/bell pepper mixture in a strainer or cheese cloth and drain as much fluid as possible.
Add it to the ground meat along with the rest of the ingredients - ginger garlic paste, tomato paste, cumin powder, paprika powder, salt, black pepper, red chili flakes, dry parsley and olive oil. Mix well.
Grab the thawed puff pastry and using a rolling pin, roll it out into a thin rectangular shape roughly 1/4 inch thin. (To prevent the puff pastry from sticking, roll it out on a silicon mat or a parchment paper).
Spread the meat mixture all over the puff pastry.
Carefully roll the puff pastry into a log, pinching the edges to seal.
Using a sharp knife, cut 14-15 pieces.
Take each piece, place on the baking tray leaving 1-2 inches space between (as they will expand).
Press them slightly to flatten them. This will create the circular pinwheel shape. They should be roughly of even thickness. (If you want to be extra sure the puff pastry won’t spread too much, put the slices back in the fridge for 15 minutes before you bake them)
Brush a small amount of egg wash on the top and sides.
Bake in the oven for 20-25 minutes until golden brown and flaky.
Serve hot with a squeeze of lemon or with your favorite dip or chutney.
