1. Cook the onion in the oil in a large skillet over medium heat for about 8 minutes, until it's soft, stirring occasionally.

2. Reduce the heat to low and cook until the onion is golden brown, about 20 minutes more.

3. Spread 1/3 of the mustard on 3 slices of bread. Add the onion mixture and beef.
