First remove the pastry sheet from a freezer and keep aside till room temperature (check instructions on box).
Take the small mixing bowl. Add chopped peppers, little salt, mix well and keep aside.
Preheat the oven on 400 F/200 C.
Now take one pastry sheet and cut into nine equal square shapes. Use same process for another sheet too. You will get total eighteen equal square sheets.
Take the muffin pan and brush or spray oil into the each muffin tin.
Place all square sheets on muffin tins and press each puff pastry square in to each of the muffin tins. You can see now they look like small bowls, see the pictures.
