First we put the oven to heat to 180 degrees because the muffins will cook quite quickly.
Put flour in a bowl and mix it with baking powder.
Beat the egg and add it to the flour together with the yogurt and oil.
We wash the pepper and cut it into small cubes. We also cut the sausages into small cubes.
Add pepper, peas, sausages and Parmesan cheese to the composition with flour. If necessary, add salt.
We mix well all the ingredients and we put the obtained composition in the muffin tins with the help of a spoon.
Put in the hot oven until lightly browned on the surface.
