Just made this for our barbeque and it was delicious. I was worried about using so much balsamic vinegar but by grilling, the strong flavor is transformed into a hint of sweetness on the veggies. We used squash, zucchini, bell peppers and crimini mushrooms. Absolutely delicious.
OH, this is sooo good! The ingredients are so simple, but it's just delicious. I cut the recipe in half for the two of us, and since it's almost winter, I used the veggies readily available: yellow squash, zucchini, red bell pepper and portabella mushrooms. I ate some of them straight out of the bowl, before they ever got to the grill. I used my indoor grill, but I'll eagerly await a chance to do it on the charcoal grill. I'm going to keep the leftover marinade and get more mushrooms tomorrow! DH agrees that this is a keeper!
