Directions

1. Peel and section grapefruit over a bowl, reserving juice. Refrigerate half of the grapefruit sections. Add remaining grapefruit to the reserved grapefruit juice. Add the lemon juice, lime juice, honey, dill, red pepper flakes and ginger. Remove 1/4 cup for basting; cover and refrigerate. Pour remaining marinade into a large resealable plastic bag; add the tuna steaks. Seal bag and turn to coat; refrigerate for 30 minutes, turning once.
2. Coat grill rack with nonstick cooking spray before starting the grill. Drain and discard marinade from tuna. Grill tuna, uncovered, over medium heat for 6-7 minutes on each side, basting frequently with reserved marinade. Top tuna steaks with reserved grapefruit sections. Cover and cook for 5 minutes or until fish flakes easily with a fork.
