Preheat the grill to medium heat, about 400°F. Clean and lightly oil the grates.
Spray the zucchini, corn, bell pepper, red onion, asparagus, and cherry tomatoes with olive oil. Season with salt and pepper.
Grill the vegetables for 3 to 4 minutes per side, until tender with light char marks. Remove from the grill and set aside.
Stretch the pizza dough into a 10 to 12-inch round. Place it directly on the grill. Cook for 2 to 3 minutes, until bubbles form and the bottom has grill marks.
Turn the crust over, and cook for another 2-3 minutes, until cooked through. Cool completely.
Spread herb cream cheese over the tops of the crusts. Add grilled vegetables.
