Step 1

To make the bun halves, add 1/4 cup egg whites/substitute to a microwave-safe mug sprayed with nonstick spray. Microwave for 45 seconds, or until set. Transfer to a microwave-safe plate. This will be the bottom bun half.

Step 2

Repeat with remaining 1/4 cup egg whites/substitute to make the top half of the bun. Evenly sprinkle bun halves with salt and pepper.

Step 3

Place cheese on the bottom bun half followed by bacon. Top with remaining bun half.

Step 4

Microwave for 20 seconds, or until cheese has melted.
