Directions
Make the egg mixture
Melt 1 tablespoon fat in a large frypan.
Add onion and green pepper and cook until tender.
Mix eggs, milk, salt, and pepper, then pour over the onion and green pepper.
Cook over low heat, stirring occasionally to let uncooked portion flow beneath cooked portion, until eggs are set but still moist.
Divide into 6 portions.
Assemble and broil
Spread toasted muffin halves with 1 tablespoon butter or margarine.
Top muffin halves with egg mixture and a slice of cheese.
Broil until cheese is melted and lightly browned, about 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a soft, moist mass that forms the body of the sandwich filling.
- Milk
- Adds moisture so the eggs stay tender rather than dry and rubbery.
- American cheese
- Melts into a smooth layer and browns lightly under the broiler.
- English muffin halves
- Provide a toasted base that holds the filling and adds crisp texture.
- Onion
- Softens during cooking and adds savory sweetness to the egg mixture.
The step that matters
Cooking the eggs over low heat. Eggs are proteins that turn firm and rubbery when overheated. Gentle heat and gentle stirring let them set into soft curds while still moist, which keeps the filling tender.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper, egg, milk, cheese):
