Preheat oven to 350F.
Throw all of the meat and veggies into a greased skillet. Cook on medium-high until the vegetables are soft.
(OPTIONAL: Season with taco seasoning. Only a few sprinkles should do it.)
Spray the muffin cups with ghee.
Put a spoonful of the meat mixture into the muffin cups.
Pour eggs in each muffin cup (about halfway full). Should cover most of the meat/veggies.
(OPTIONAL: Sprinkle crushed red pepper flakes on top to spice things up.)
Bake for about 15 minutes (or until eggs are firm and cooked all the way through).
Let them sit for about 5 minutes at room temperature before transferring them to a container or bag for freezing.
