Mojito-Marinated Chicken Kebabs

Preheat grill to medium-high.

Combine mint, lime juice, oil, rum, agave, 1/4 teaspoon salt and pepper in a mini food processor. Pulse until well incorporated, about 15 seconds. Reserve 2 tablespoons for serving; pour the rest into a medium bowl. Add chicken and toss to coat. Let stand for 10 minutes.

Cut onions into 1-inch rounds, then into quarters. Thread the onions and chicken onto separate skewers. (Save the leftover marinade.)

Grill the chicken for 8 minutes. Turn and brush with the leftover marinade and grill until an instant-read thermometer inserted into the thickest part registers 165 degrees F, about 8 minutes more. Grill the onions, turning occasionally, until slightly charred, about 4 minutes per side.

Sprinkle the chicken and onions with the remaining 1/4 teaspoon salt and drizzle with the reserved 2 tablespoons marinade. Serve with lime wedges and more mint, if desired.
