Preheat the oven to 350. If using a muffin pan that needs greasing, spray it with nonstick cooking spray.
Assemble your ingredients so you don't forget anything. Cook, slice, or shred whatever needs prepping.
Beat the eggs in a large mixing bowl and season to taste with salt and pepper. Add the mix-ins. Stir well to combine.
Scoop the mixture into mini muffin pans. Bake for 20 minutes. Remove to a rack or platter and serve.
Notes
To freeze: allow the bites to cool completely. Wrap, label, and chill in the refrigerator until very cold before storing in the freezer. To serve: reheat in the microwave or allow to thaw in the refrigerator to eat cold or at room temperature.
