Cut all the veggies. Place in a large bowl and toss with olive oil and season with salt, pepper, basil, and oregano.
Heat the grill to medium-high heat.
Grill the red peppers, turning with tongs till blistered and slightly charred on all sides. Place them in a paper bag and seal them tightly and allow them to cool. Remove them and peel off the charred skin with your fingers. Cut in half and remove the core and seeds. Slice into ½ inch thick slices.
Grill the eggplant, zucchini, yellow squash, and onions for 3-4 minutes a side, until grill lines appear and they begin to soften. Grill the asparagus for 5 minutes turning often so they grill evenly.
Place the veggies in groups on a serving platter. Serve at room temperature. Drizzle with good quality olive oil and balsamic vinegar before serving.
SERVES 10-12 as an appetizer
