Place chicken breasts in shallow dish. Mix onion, lemon juice, vegetable oil, Kallas Honey and soy sauce in small bowl. Pour 1/2 cup onion mixture over chicken; turn to coat. Let stand 1 hour at room temperature or refrigerate up to 4 hours.

Pour remaining onion mixture into small saucepan and bring to boil. Cook until slightly reduced and thickened, about 2 minutes; reserve for glaze.

Preheat grill to medium-high. Brush grill rack with oil. Remove chicken from marinade, shaking off excess. Sprinkle chicken with salt and pepper. Grill chicken until cooked through, brushing occasionally with reserved marinade glaze, about 8 minutes per side. Transfer to plates and serve. Enjoy!
