Beefed Up Kebobs

• 1/3 c red wine vinegar
• 1/4 c ketchup
• 2 tbsp olive oil
• 2 tbsp soy sauce
• 1 tbsp Worcestershire sauce
• 1 tsp Dijon mustard
• 1 tsp salt
• 1/4 tsp freshly ground pepper
• 2 cloves garlic (I use the bottled minced garlic & use about a tbsp)
• 1 lb sirloin cubes

Combine all marinade ingredients and mix well. Place beef (and chicken) in a shallow non metallic container (I use a 9×13 glass dish) Marinate, covered, in the refrigerator for 2 hours or longer, turning occasionally. Remove meat from pan and put on skewers. I alternate chicken and beef but you could do them on separate skewers if you like. You could also add vegetables to the marinade and alternate them with the meat if you like as well. Grill or cook in the rotisserie till done.
