Cheese Muffins

Preheat the oven to 180°C and grease or line a muffin tin with paper liners.

In one bowl, mix together the flour, baking powder, baking soda, salt, and ground pepper. Add the grated cheese and ham or bacon, if using, to the dry ingredients and mix.

In another bowl, whisk the eggs, add milk, oil (or melted butter), and if using, also add Dijon mustard and chopped herbs. Mix the mixture well.
