Take 2 bowls, add in one of them the egg, sunflower oil and milk.
In the other one add flour, baking powder, salt and pepper
Mix the contents of the bowl seperately
When mixed, add the contents together in 1 bowl and mix to a dough
Then add the bacon (no need to fry these first) and grated cheese and fold into the batter
I also added some chorizo sausage for extra flavour
Fill the muffin tin with the batter
Put some grated cheese on top
Bake the muffins 12-15 minutes on 200 degrees Celcius until done and golden brown
Enjoy!
