Heat the oven to 350 F (175 C).
Coat a muffin pan or 12 muffin forms with a little cooking spray.
Wrap a slice of bacon around the inside of each of the muffin forms and put a little spinach at the bottom of each.
Chop onions, jalapeno, and garlic finely and sauté for a few minutes until the onions are translucent.
Take the onion mix off the stove and divide evenly between the 12 muffin forms, placing it on top of the spinach.
Chop the sausage and bell pepper and add to the muffin forms.
In a mixing bowl, combine egg whites, whole eggs, salt and pepper and whisk them together.
Pour the egg mixture into the muffin forms so it just covers the veggies.
Bake for 25 minutes on the middle rack.
