Relish:
2/3 cup finely chopped peeled cucumber
1/2 cup finely chopped red bell pepper
1/4 cup finely chopped red onion
1 tablespoon fresh lime juice
1 tablespoon honey
1 teaspoon finely chopped dill
1/8 teaspoon salt
Dash of ground red pepper
Burgers:
1 (15-ounce) can black beans, rinsed and drained
1/2 cup dry breadcrumbs
1/4 cup minced red onion
1/2 teaspoon dried oregano
1/4 teaspoon ground cumin
1/8 teaspoon black pepper
1 large egg
Cooking spray
1/4 cup light mayonnaise
4 (1 1/2-ounce) hamburger buns
Dill sprigs (optional)

Preparation:
To prepare relish, combine first 8 ingredients in a medium bowl. Cover and chill 2 hours.

To prepare burgers, place beans in a large bowl; partially mash with a fork. Stir in breadcrumbs and next 5 ingredients (breadcrumbs through egg).

Divide bean mixture into 4 equal portions, shaping each into a 1/2-inch-thick patty.

Prepare grill. Place patties on grill rack coated with cooking spray; grill 5 minutes on each side or until thoroughly heated. Spread 1 tablespoon mayonnaise on the bottom half of each bun; top each with a patty, 1/4 cup relish, and top half of bun. Garnish with dill sprigs, if desired.
