Grease a muffin pan liberally. These tend to stick, so you can also use a cupcake liner, but add 5 minutes to 20 minute cook time. Place 3 frozen tater tots in the bottom of each muffin tin and bake for 10 minutes.
Top each cup with about 1/2 tablespoon of diced ham and 1/2 tablespoon of diced peppers. Whisk together the eggs and milk and pour the mixture into each muffin tin nearly to the top.
