Preheat the oven to 350 degrees. Prepare a 12-count muffin tin with non-stick spray, butter, or muffin liners.
Whisk 12 eggs in a bowl until they are broken down.
Add the cooked vegetables, cheese, meat, and spices and whisk.
Fill each muffin cup to ⅔ full and bake at 350 degrees for 18-20 minutes, or until the eggs are set.
Let the egg cups cool for about 5 minutes and then serve immediately. These can be stored in the fridge for 3-5 days in an airtight container.
You can also wrap them individually or in sets of two in plastic wrap and place in a freezer bag in the freezer for about 3 months. Allow them to thaw in the fridge overnight or for a few hours and then heat in the microwave for 30 seconds to 1 minute.
