Preheat oven to 350F degrees. Spray a muffin tin with nonstick cooking spray.
Place individual ham slices over each muffin cup and gently press down in the middle until a cup shape forms.
In the bottom of each ham cup, add in about a tablespoon of shredded cheddar cheese.
In a medium bowl, whisk eggs together. Stir in sliced green onions and salt and pepper, to taste.
Add a couple of tablespoons of the egg mixture into each of the ham cups.
Place muffin tin in the oven and bake for about 20-25 minutes.
When done, use a fork to gently remove each ham cup and serve.
