Preheat to 400F. Grease a standard 6-cup muffin pan, preferably nonstick, with avocado/olive oil or coat with cooking spray.
Add the eggs, quinoa, peas, green onions, herbs, and pepper to a large bowl and combine well with a fork.
Season generously with salt and pepper. Divide the mixture equally among the muffin cups, about 1/3 cup for each, filling until almost full.
Bake until the muffins have puffed up and turn light golden on top, about 15-20 minutes.
Once cooked, gently release each muffin from pan.
