We like to Bar-B-Que. A lot. I especially like the part where there is one less pan to wash. So, here is a recipe we use often.
Sir loin steaks, cubed
Mushrooms (My favorite part!)
Whatever else you like, such as potatoes, yellow squash, etc
Your favorite marinade
Cut up the meat and put it in the bowl with marinade. Let it sit in the fridge a couple of hours. Cut up the veggies, put them in a different bowl with marinade. They don't have to sit as long. When you are ready, spear the ingredients with the skewer and place on the bbq. I make some pretty ones with a pattern, but mostly I make them all single-ingredient. For instance, the potatoes and zucchini can take longer to cook than the onions, so if you put them on different skewers you can cook them longer. Brush the skewers with the left over veggie marinade while they are cooking. I suppose you could use the meat's marinade, but I worry that the marinade that had raw meat in it won't get heated enough if you brush it on top of the skewers while they cook, so we use only the left over veggie marinade just to be on the safe side.
