Preheat the grill to high heat.

Toss the vegetables in olive oil (plan on about 1 tablespoon per pound of vegetables), and season with salt and pepper, to taste. Brush the oil over the red onion in order to keep the slices in tact.

Reduce the grill heat to medium high. Add the vegetables and grill the shishito peppers 2-3 minutes turning once, 6-8 minutes for the bell peppers, eggplant, poblano pepper and zucchini, turning once, 12-15 minutes for the carrots and corn, turning on each side till charred. Remove from heat and let stand covered loosely with foil for a few minutes until cool enough to handle.

Chop or slice as needed to serve as a side dish with dressing or use in recipes such as salads, pasta, sandwiches, dips and more!
