Use cooking spray to coat the grill, or brush lightly with olive oil.
Preheat the grill to a medium high setting.
Combine parsley, lemon juice, oil, garlic, and all seasonings in a bowl.
Add the vegetables and toss to coat them thoroughly.
You can marinate the veggies for up to 2 days, or grill right away.
Place the vegetable rack or a screen on the grill and then place the coated vegetables on the rack.
Grill for about 15 minutes, turning the basket or screen over frequently.
Veggies should be tender and slightly charred when done.
