I used 2 small zucchini, 1 small onion, and one 8 oz carton of slice mushrooms for 4 side dish servings. This dish would also be good with bell pepper, yellow squash, or eggplant, there are so many delicious combinations.
Now comes the fun part- hang out on your deck or patio and grill your veggies. Maybe have a beer or glass of wine? The veggies can take anywhere from 15-30 minutes depending on how you like them. I like mine pretty well done- soft with a little char. Mmm!!
