Several years ago a co-worker brought a similar dish to a potluck. It's a bit of a different twist on roasted vegetables. A balsamic vinaigrette is poured over the vegetables before they are roasted, resulting in more depth of flavour. This dish is great warm, cold, or hot. I'm planning on taking it on a camping trip soon.
The amounts given here are generous and will serve 8 - 10 people. Add or subtract vegetables as you like. I think butternut squash, sweet potatoes, yellow summer squash or mushrooms would be fine additions. You may have to adjust the baking times depending on the vegetables chosen.
Balsamic Roasted Vegetables
2 medium sized zucchini, ends trimmed and cut into a 1 inch dice
2 medium eggplant, peeled and cut into a 1 inch dice
1 large red or white onion, cut into a 1/4 inch dice
2 sweet red bell peppers, cut into 1/2 inch dice
2/3 cup olive oil
1/3 cup balsamic vinegar
2-3 cloves garlic, minced
1 teaspoon salt
1 teaspoon freshly ground black pepper
fresh basil or parsley
Combine the zucchini, eggplant, onion and peppers in a large bowl.
Whisk together the olive oil, balsamic vinegar, garlic, salt and pepper. Pour over the vegetables. Hold about 1/4 cup back, for dressing the vegetables later, if desired. Use enough to coat the vegetables, but they shouldn't be sitting in a puddle of dressing
Spread on two rimmed baking sheets. Roast at 450 degrees Fahrenheit for 20 minutes, then stir and continue roasting 10-15 minutes. The vegetables should be lightly browned and beginning to caramelize around the edges.
Cool. Add 1-2 Tablespoons of fresh minced parsley or julienned basil just before serving.
