     1/2  cup           olive oil
   1      tablespoon    rosemary -- chopped, fresh

Combine the lemon juice, olive oil, rosemary, garlic, salt, pepper and vinegar in a mixing bowl. Place the hen halves in a shallow dish and pour half of the mixture over them. Turn to coat.

Grill 6 inches from a hot fire for 10 minutes per side, turning once and basting with the remaining marinade.
