Step 1: Prepare the Bread

1. Use a round cookie cutter, glass, or biscuit cutter to cut a hole (about 2 inches wide) in the center of one slice of bread. Keep the cut-out piece for extra toasting!

Step 2: Cook the Egg-In-A-Hole

1. Heat 1 tablespoon of butter in a skillet over medium heat.
2. Place the hole-cut slice of bread in the pan. Crack 1 egg directly into the hole and season with salt and pepper.
3. Cook for 2-3 minutes, until the egg begins to set. Flip gently using a spatula and cook for another 1-2 minutes for a soft yolk or longer for a firm yolk.
4. Toast the second slice of bread in the pan until golden brown.

Step 3: Assemble the Sandwich

1. Place one slice of cheese on the toasted bread slice.
2. Add cooked bacon (or sausage), avocado slices, and tomato.
3. Gently place the egg-in-a-hole toast on top.
4. Add the second cheese slice and close the sandwich.

Step 4: Final Toasting

1. Place the whole sandwich back in the skillet for 30-60 seconds per side, allowing the cheese to melt and the bread to crisp up.
2. Remove from heat, slice in half, and serve immediately!
