Homemade beef kabobs are the perfect dish to serve for your next outdoor dinner party. These kabobs can be prepared and stored in the fridge up to two days before you're ready to grill them, which makes them ideal for entertaining.
Soak skewers in water 30 minutes. Meanwhile, place bread and water to cover in a small bowl; let stand 10 minutes. Using hands, squeeze excess liquid from bread; transfer bread to a large bowl. Stir in beef and next 9 ingredients.
Coat cold grill grate with cooking spray. Preheat grill to 400° (medium-high) heat. Divide ground beef mixture into 8 portions, and chill 10 minutes. Press and flatten each portion around a skewer, forming a 4- to 5-inch oval.
Grill, covered with grill lid, 7 to 8 minutes or until golden brown, turning once. Serve warm with pita rounds, Yogurt-Tahini Sauce, and Herbed Cucumber-and-Tomato Salad.
MAKE IT AHEAD Prepare these kabobs up to two days in advance, and store in the fridge. Pop them on the grill just before you're ready to serve.
