How to Make It
Preheat grill to medium-high heat.
Combine 3 tablespoons oil, vinegar, honey, rind, pepper, and salt in a small bowl, stirring with a whisk.
Wrap okra halves with prosciutto strips. Thread wrapped okra onto 8 (12-inch) skewers. Brush wrapped okra evenly with remaining 1 tablespoon oil.
Place okra on grill rack coated with cooking spray; grill 8 minutes or until prosciutto is crisp and okra is crisp-tender, turning once after 4 minutes. Brush wrapped okra with half of balsamic mixture; grill 1 minute. Remove from heat; drizzle with remaining balsamic mixture.
