Method:
1. Preheat the oven to 350° F.
Grease a 12-cup muffin tin.
2. In a large bowl, whisk together the eggs, milk, cheese, salt, and pepper.
3. Divide the basic muffin mixture evenly among the cups of the muffin tin.
4. Choose one of the flavor options and stir the additional ingredients into the muffin cups.
5. Bake the muffins until they are set and the edges are golden brown, about 20-25 minutes.
6. Let the muffins cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely. Enjoy!
