Preheat the oven to 350 F. In the skillet over medium heat, melt a knob of butter. Add 2 chopped bacon strips, 1 sausage link, and 2 slices of ham, chopped. Cook until the sausage is done, 5 minutes or so.

Drain excess fat from the pan. Then add a big handful or two of baby spinach; stir until just wilted, 1 minute. Beat and add 6 large eggs. Cook until the eggs have set, 3-4 minutes and transfer the skillet to the oven.

Bake everything until you can shake the skillet and the eggs don’t jiggle, 8-10 minutes. Using a kitchen towel carefully remove the frittata from the oven. Let it cool a bit, transfer to a cutting board, slice, and serve.
