1 1/2 c. salad oil
1/2 c. soy sauce
1/4 c. Worcestershire sauce
2 tbsp. dry mustard
2 tsp. salt
1 tbsp. coarse ground pepper
1/2 c. red wine vinegar
1/3 c. fresh lemon juice
1 1/2 tsp. dried parsley flakes
2 crushed garlic cloves (I usually omit garlic cloves and salt and use garlic salt instead!)

Combine ingredients. Pour over 1 1/2 inch chunks of beef and marinate in refrigerator overnight.

Allow about 6 ounce of beef per person. Prepare skewers by alternating the beef chunks with uncooked shrimp, sweet onions, green peppers, pineapple chunks, whole mushrooms and cherry tomatoes. Grill for 12-14 minutes, basting and turning frequently.
