There's something primaly satisfying about eating grilled meat (or veggies, I guess) off of a stick, but skewering lamb meat can quickly turn into skewering hand meat if you're not careful. Luckily, Serious Eats has come up with a faster, safer way to kebab cubes of food, and all you need is half an onion.
Actually, a potato or lemon would work to. All you need is half of a firm, stable piece of produce. To skewer, place your piece of marinated meat on the onion half and stab. (If you're at all confused about the process to see a GIF of J. Kenji Lopez-Alt in action.) Repeat with the next piece until you have enough meat on your stick. Grill and eat using your not-stabbed hands.
