Serve over hot cooked rice to catch all the delicious juices.

1 pound high-quality beef chuck, tip or round, 1 inch thick
1/2 pound beef liver, 1 inch thick
1/4 cup lemon juice
3 tablespoons vegetable oil
1 clove garlic, chopped
1 1/2 teaspoons onion salt
1/4 teaspoon ground ginger
1/8 teaspoon crushed red pepper

Cut beef and liver into 1-inch cubes. The meat cuts easier if partially frozen. Place meat in a non-reactive bowl. Mix remaining ingredients; pour over meat. Cover and refrigerate, stirring occasionally, at least 6 hours. 

Thread beef and liver cubes on each of 6 skewers. Brush with marinade. Set oven to broil or 555 degrees F. Broil kabobs with tops 4 inches from heat 5 to 6 minutes; turn. Brush with marinade; broil 5 to 6 minutes longer.
