* Prepare grill to medium-high heat. Cut 1 English cucumber into thirds crosswise; cut each piece into quarters lengthwise. Grill cucumber 6 minutes or until lightly charred and crisp-tender, turning occasionally. Place cucumber in a bowl. Add 1 tablespoon rice vinegar, 1 teaspoon dark sesame oil, 1/4 teaspoon kosher salt, and 1/8 teaspoon crushed red pepper; toss gently to combine.
