I do veggies a lot on the grill specially in the spring/summer: asparagus, Brussel sprouts, taters, onion summer squash,green beans, sweet peas what Evers in season cut and put in a foul pan with oil
In the winter I do them on a cookie sheet in the oven toss everything in salt and olive oil spread on a cookie sheet and cook at 350 or the good ol cast iron skillet
