- Broil or grill to your liking, about 4 minutes on each side.

When you put the relishes inside of the hamburger, it not only make serving much simpler, but the meat stays juicier. You can broil, pan fry or cook them on the grill, just be sure to seal the edges well.

TIPS:
Patties may be prepared ahead and refridgerated until ready to serve, up to 6 hours ahead of time. If made any earlier then that the filling may start to taste "OLD".
