Given your supposed vegetarian health kick you would do well to marinade cubes of meat in garlic, lemon juice/zest, chilli, various herbs you have to hand and griddle on a hot pan and serve with salad and a low fat yogurt tzaziki.
Kebab Meat is traditionally beef, lamb (mutton), chicken, and/or even veal that is arranged in a cylindrical fashion on a large skewer that turns in front of a heat source. It is cut and served as it cooks. http://tinyurl.com/b5fzju5
