Place a piece of each different type of meat on each skewer. Season with salt. In a small mixing bowl, combine the water, salt and garlic. Place the skewers in a shallow bowl. Pour the marinade over the meat, cover and refrigerate for at least 2 hours or overnight. Remove and bring to room temperature. Preheat the grill. Remove the meat from the pan, reserving the marinade. Place the skewers on the grill and cook for 3 to 4 minutes on each side, basting often. Remove from the grill and cool for a couple of minutes before serving. Serve with Vinaigrette.
Combine all ingredients in a mixing bowl. Mix well. Allow to sit for at least 1 hour before serving.
