Skewers and kebabs are easy to make, and assembling them isn’t hard, but anyone who’s poked themselves on a skewer knows it can still suck. Luckily, all you need to speed up the process (and make it safer) is an onion—one you may be using anyway.
I’ve been using Alton Brown’s method – the episode of Good Eats is on Netflix.
Hold the veggie/meat with one hand on a surface (like a cutting board), then push the skewer in with your other hand parallel to the surface. Also, instead of having alternating items on each skewer, which looks pretty, I made my skewers of each ingredient, which came in very handy to move whole skewers around my grill on and off heat as they needed. Much less over cooked X and underdone Y.
