Balsamic Grilled Vegetables

OMG, these were SO amazing--and SO easy!

I got the recipe from Food Network (of course) at this link:
http://www.foodnetwork.com/

and made a few adjustments in the veggies I used.

Recipe, from the link:

1 medium yellow squash, sliced on bias
1 medium zucchini, sliced on bias
1 medium eggplant, sliced into 1/2-inch thick circles
1 red onion, sliced in 1/2-inch thick circles
2 Roma tomatoes, sliced in 1/2 lengthwise
1 red bell pepper, stemmed, seeded, and quartered
1 yellow bell pepper, stemmed, seeded, and quartered
2 portobello mushroom caps, gilled and peeled
3 green onions
Kosher salt
Freshly ground black pepper
1/2 cup extra-virgin olive oil
1/2 cup balsamic vinegar
Preheat grill to high.

Prepare all vegetables. Place vegetables in a roasting pan with the mushroom caps and green onions. Season vegetables generously with salt and pepper, and toss with the olive oil and balsamic vinegar. Place vegetables, cut side down, on the hot grill and cook for a couple minutes on each side, or until tender and nicely marked by the grill.

Remove from grill and toss with an additional 1/4 cup balsamic vinegar. Season with salt and pepper, to taste.

(me again)

I don't care for eggplant, so skipped that
We don't have NICE, garden-fresh tomatoes yet, so I skipped that, too. I used:
asparagus
fennel bulb
zucchini
purple onion in thick slices
green onions, whole
portobello mushroom caps
red bell pepper
cubanelle pepper

For the peppers, I roasted them whole over the grill, then wrapped them in a bowl covered with saran wrap until the skin slid off. Next time I'll do that early and then cut them and return them to the grill, but this time I didn't. They had less grilled flavor that the other things, but were still yummy.
