In a large cast iron skillet over medium heat, brown the ground beef until fully cooked. Drain off any excess fat.
Add the scallions and green chiles and give everything a good stir. Turn off the heat.
Whisk together 6 eggs in a mixing bowl. Stir in the cheddar cheese. Dump the egg and cheese mixture into the skillet.
Place the skillet in the oven and bake for 10-12 minutes, or until eggs are fully cooked through (test with a knife through the center). Eat as-is, topped with salsa, or topped with a keto-friendly ketchup.
