Preheat oven to 350°.
Spray vegetable spray into 4 regular sized muffin tins. Place a slice of canadian bacon in each of the prepared tins and press it into the muffin form.
Chop the bell pepper into 1/2" dice and divide evenly among the muffin tins.
Whisk the eggs in a small bowl and season with the salt and pepper. Divide the eggs among the muffin tins. Sprinkle each of the egg cups with cheese and bake for 12-15 minutes until the center is just set. Turn up the oven to broil and continue to cook for 1-2 minutes to brown the top lightly. Remove from the oven and let rest for 1-2 minutes. Use a sharp knife to loosen the edges of the egg cups and transfer to a platter or plate. Sprinkle with parsley or chives and serve.
