In a shallow container with a lid add the ingredients of the marinade and mix well until combined.
Trim the beef of any fat and cube into 2x2x1 inch pieces. Add to the marinade and stir to coat well. Refrigerate for 3 hours or overnight.
Take a skewer and add mushrooms, beef, peppers, water chestnuts and onion alternating each. Repeat for the rest of the skewers until all meat is used.
These can be made in the oven on medium broil for 12-15 minutes turning every 5 minutes or on the BBQ over medium high heat cooking for 12-15 minutes turning and basting often with marinade. Grill until the beef is cooked and the vegetables are tender.
Notes
These can also be made in the oven on medium broil about 5 inches from the heat. Cooking for 12-15 minutes turning often.
The beef kabobs go well with a wonderful side salad.
