Step 1

In a wide bowl, mix egg whites/substitute, vanilla extract, and cinnamon.

Step 2

Open bun without separating the halves. Spread peanut butter onto one half, top with jelly or preserves, and lightly press to seal. Slice into four "nuggets."

Step 3

Bring a skillet sprayed with nonstick spray to medium-high heat. Add butter and let it coat the bottom.

Step 4

Meanwhile, coat nuggets on all sides with egg mixture.

Step 5

Cook nuggets, flipping occasionally, until golden brown on all sides, 3 - 4 minutes.
