Preparation

In a bowl, combine the first eight ingredients and mix well. Pour 1 cup into a shallow dish; add vegetables. Pour remaining marinade into another shallow dish; add beef. Cover and refrigerate both for 4-6 hours or overnight, turning occasionally.

Drain and discard marinade from beef. Drain and reserve marinade from vegetables. On metal or soaked wooden skewers, alternately thread beef, tomatoes, mushrooms, zucchini and summer squash.

Grill, uncovered, over medium heat for 3 minutes on each side. Baste with reserved marinade. Continue turning and basting for 8-10 minutes or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°). Serve kabobs over rice if desired.
