Step 1If using disposable wooden skewers, soak the skewers in water for about 10 minutes before using.
Step 2To prepare the skewers, alternate paired meat cubes and bay leaves with the pieces of pepper, tomatoes and onion wedges. (You can put a couple of sacrificial lamb chunks at one of the ends so the cook can easily taste-test for doneness.) Lightly brush the prepared skewers with olive oil, and season each large skewer with one-half teaspoon salt and a pinch of pepper.
Step 3Grill each skewer over a medium-hot grill or broil for 5 minutes, then turn over and cook the other side an additional 5 minutes, or to desired doneness. Remove and allow the meat to rest for a few minutes. Serve with more sea salt, pepper and generous wedges of fresh lemon.
