Spinach and Feta Turkey Burgers with Cucumber Relish

For cucumber relish, combine cucumber, onion, sugar, vinegar, lemon juice, salt, and the pinch ground pepper in a small bowl. Cover and chill for at least 30 minutes.

Place one of the hamburger buns in a food processor or blender. Cover and process or blend until crumbs are formed. Measure 1/2 cup of the crumbs; set the remaining crumbs aside for another use. Toast the remaining six buns.

Combine the 1/2 cup bread crumbs, the spinach, feta cheese, egg product, the remaining 1/4 teaspoon ground pepper, and the cayenne pepper in a large bowl. Add turkey breast; mix well. Shape turkey mixture into six 4-inch patties.

Heat oil in a 12-inch skillet over medium-high heat. Add turkey patties. Reduce heat to medium. Cook patties for 12 to 14 minutes or until patties are no longer pink (165 degrees F; see Tip), turning once halfway through cooking time.

Serve patties in toasted buns. If desired, top with sliced tomatoes. Serve with the chilled cucumber relish.
