Heat oven to 350°F. Coat muffin pan with cooking spray.  Pile tortillas on top of one another and cut into a circle that is approximately 3 1/2 - 4 inches wide.  Or, place each tortilla over the muffin cup, press in, then cut off the excess.  Set aside.

Chop all veggies, set aside separately, especially if not all family members are fond of all the veggies in their eggs.

In a large bowl, whisk together the eggs and sour cream until smooth.  Mix in 1/2 the cheese, salt and pepper.

Place cut tortillas into each of four muffin cups and pour in the egg mixture.  Sprinkle the desired veggies on top.

Bake for 10 minutes and, if more cheese is desired, sprinkle on top at this time.  Bake for 3-5 minutes longer, until the egg is completely cooked and the tortilla becomes browned.

Serve warm with banana slices on the side.
