For the savory feta muffins, divide the pizza dough into small squares.
Fill each square with the tomato pesto, then with the chopped onion, feta and tomato. Then press the corners of the dough together to make small pockets.
Then place these in muffin tins and sprinkle with the grated mozarella cheese and oregano.
Bake the spicy feta muffins in the oven at 180°C until the mozarella cheese has melted and is crispy.
