Preheat oven to 375℉.
Spray a muffin pan with non-stick spray, then line each cup of the pan with a slice of ham.
Remove the thick stem from kale or chard leaves, and tear leaves into 1-2 inch pieces.
Place a thin layer of greens in each cup.
Crack an egg in each cup (If you are worried about shells, crack the egg into a small bowl and then pour into the muffin cup.)
Season with salt and pepper.
Bake about 15 minutes, until eggs have set.
Allow baked eggs to cool for a few minutes before removing from pan.
Serve warm.
