Step 1

Lightly toast bread or broil for 1 to 2 minutes on each side.

Step 2

Preheat oven to 400°F. If using a toaster oven adjust the cooking rack to the bottom placement and select the BAKE setting.

Step 3

Crack the egg into a small bowl and beat with a fork until the yolk and white are combined. Mix in the cheese and fresh herbs if using. Add salt and pepper as desired. Spread mixture over the bread all the way to the crusts. Sprinkle with cayenne.

Step 4

Bake until the cheese and egg mixture is puffed, bubbly, and starting to brown, about 10 to 12 minutes.
