# Ingredients:

For the breakfast sauce

01 - 1/3 cup (75 g) mayonnaise
02 - 1 tablespoon yellow mustard
03 - 1 tablespoon steak sauce
04 - 1 teaspoon lemon juice
05 - 1/4 teaspoon dried dill
06 - 1/4 teaspoon black pepper

For the sandwiches

07 - 4 plain, onion, or everything bagels, split
08 - 1 lb (450 g) thinly sliced ribeye, sirloin, or shaved beef
09 - 1 tablespoon Worcestershire sauce
10 - 1 teaspoon garlic powder
11 - 3/4 teaspoon kosher salt, divided
12 - 1/2 teaspoon black pepper
13 - 3 tablespoons (42 g) unsalted butter, divided
14 - 1 medium yellow onion, thinly sliced
15 - 4 large eggs
16 - 8 slices American cheese

# Instructions:

01 - Stir together the mayonnaise, yellow mustard, steak sauce, lemon juice, dill, and black pepper. Refrigerate while you cook the sandwich fillings.
02 - Toss the thin steak with Worcestershire sauce, garlic powder, 1/2 teaspoon salt, and black pepper. Let it sit while the onions start cooking.
03 - Melt 1 tablespoon butter in a large skillet over medium heat. Add the sliced onion and cook for 7-9 minutes, stirring often, until soft and golden. Transfer to a plate.
04 - Increase the heat to medium-high. Add 1 tablespoon butter and the steak in an even layer. Cook for 2-4 minutes, turning once or twice, until browned and cooked through. Move the steak to the plate with the onions.
05 - Beat the eggs with the remaining 1/4 teaspoon salt. Melt the remaining 1 tablespoon butter in a nonstick skillet over medium-low heat, add the eggs, and cook until just set. Fold into four squares.
06 - Toast the split bagels until the cut sides are golden. Spread sauce on both sides of each bagel.
07 - Layer one slice of cheese, steak, onions, folded egg, and a second slice of cheese on each bottom bagel. Add the tops and let the hot fillings melt the cheese for 1 minute before serving.

# Good to know:

01 - Best served hot right after assembly.
02 - Freeze the steak for 15 minutes before slicing if cutting it from a whole piece.
03 - The sauce can be made up to 3 days ahead.
