Grilled Chicken Breast with Cucumber Relish

Description

4 boneless, skinless chicken breasts (2 pounds total), pounded 1/2 inch thick
Kosher salt and freshly ground pepper
3 mini cucumbers, chopped (1 cup)
1 scallion, thinly sliced
1/2 red jalapeÃ±o (ribs and seeds removed for less heat, if desired), halved and thinly sliced
1/4 cup unseasoned rice vinegar
2 tablespoons sugar
Vegetable oil, for grill
2 tablespoons extra-virgin olive oil
1/4 cup fresh mint leaves, for serving

Step 1

Season chicken on both sides with salt and pepper. Let stand at room temperature 30 minutes, or refrigerate, covered, up to 2 hours. Meanwhile, combine cucumbers, scallion, jalapeÃ±o, vinegar, and sugar. Season with salt.
Step 2

Heat grill to mediumâ€high; lightly brush grates with vegetable oil. Rub chicken with olive oil; transfer to grill. Cook about 2 minutes, then rotate chicken 45 degrees (to create crosshatch marks) and continue cooking another 2 minutes. Flip and grill until cooked through, 3 to 4 minutes more. Transfer to a platter; let stand 10 minutes. Serve with cucumber relish and mint.
