Mash drained black beans (food processor or potato masher work well). Combine with all ingredients except eggs and oats. Once mixed well add eggs until thoroughly mixed (it's really easier to do this by hand even though it's a bit messy). Once mixed add oats (you may need slightly more oats depending on consistency, mixture should hold together fairly well and not be too mushy). Shape into 2-3 inch balls and press flat to form a patty. Place on hot fry pan sprayed with nonstick cooking spray. Cook until browned on both sides (3-4 minutes per side). Serve on a bun with cheese, on a bed of fresh greens, or let cool and store in fridge for later use.
