We are still in the height of "grilling season" and shish kebab cooking is quick and easy. If making kebabs with chicken or meat, you will want to make sure that you cut uniform pieces of 1-2" and refrigerate in your favorite marinade following your favorite recipe directions.
Wooden kebab skewers can be found in any grocery store. Before using on the grill, you MUST soak them in water BEFORE skewering your meats and/or vegetables to prevent the wood from burning on the grill. You can even cover the tips of the wooden skewers with small pieces of aluminum foil.
If you do a lot of grilling this way, consider investing in stainless steel skewers. They may cost a little more initially, but they can be used over and over again.
