In a bowl, combine ground beef, chopped onion, one egg, salt, and pepper. Form into 4 patties.

Heat a skillet over medium heat. Cook patties 4–5 minutes per side or until fully cooked. Remove and set aside.
In the same skillet, melt butter. Add the mushrooms and sliced onions, cooking until softened.
2 tablespoons butter, 1 cup sliced mushrooms, ½ small onion
Sprinkle the flour over the vegetables. Stir and cook for 1 minute. Slowly whisk in beef broth and soy sauce. Simmer until thickened, about 5–7 minutes. Season with salt and pepper.

In a separate pan, heat oil over medium heat. Fry eggs sunny-side up or to your preference.
