If you want, you can top the egg bites with salsa, some hot sauce, guacamole, or cottage cheese.
It's important to allow the egg bites to cool before you add them into the bag or it will create moisture in the bag which will affect the texture of the egg bites.
Suggestions for what to put in egg bites:
diced green or purple onions, chopped red or green pepper, pre-cooked deli ham, pre-cooked sausage, crumbled cooked bacon, cooked diced turkey, shredded cheese (cheddar, Gruyere, Swiss, jalapeño jack, or a blend), diced jalapeños, spinach, broccoli
