1. Preheat oven to 400° F. Using a basting brush, lightly oil a muffin pan and place on a sheet pan.
2. In a bowl, whisk eggs and seasoning. Pour into muffin cavities, filling each about ¾ full. Sprinkle with cheese and add your chosen fillings, if desired.
3. Bake 15 min or until eggs are set. Let cool slightly before removing from cavities.
4. If making ahead, refrigerate up to 5 days or freeze up to 1 month.
