1. Begin by draining and rinsing the beans. Set aside.

3. Combine 3/4 of the beans, oats, tomato paste, salt, pepper, mustard and Worcestershire sauce in a food processor and pulse until mashed.

5. Scoop out between 3/4 cup of the bean mixture and form into a ball. Place the ball on a piece of wax paper.  Do this 3 more times.
