In a skillet over medium to medium high heat, melt one teaspoon of the butter and add the sliced steak and onion.
When the onion is a little translucent but still crunchy, add the soy and Worcestershire sauces, stirring well to coat all of the onion and steak.
Sprinkle a little garlic and herb powder to taste.
Cook just until the steak and onion are beautifully caramelized and heated through. You want that little texture and crunch left in your onions.
Transfer to a dish while you prepare your egg.
In the same skillet or a fresh skillet, melt the remaining teaspoon of butter and fry your egg to taste. Season with salt and pepper.
Serve over the steak and onion mixture.
