Add margarine to the frying pan and melt the margarine. Add the bread crusts and coat the pieces.
When all the margarine has been absorbed by the bread crusts, add the granulated sugar. Roast until the bread crusts are crisp and all the moisture has evaporated.
Turn off the heat, sprinkle with granulated sugar to garnish, and set aside until cooled.
Story Behind this Recipe
I had a lot of leftover bread crusts after making sandwiches.
You can use butter instead of margarine! Butter adds depth to the flavor, and is great as well. When you roast the bread crusts in the frying pan, be careful not to burn them If you burn them, they will turn bitter.
