Preheat oven to 375°F. Unroll each sheet of crescents on a half sheet pan, joining the seams in the center. Bake for 12-14 minutes or until crust is golden brown and puffy. Remove from oven and allow to cool.
Meanwhile, beat together the cream cheese, yogurt, mayo, onion powder, garlic, dill and parsley. Season to taste with salt and pepper.
Spread the cream cheese mixture evenly over the crust. Top with shredded cheese, if desired.
Sprinkle the veggies evenly over the crust and press them in a bit. Cover with saran wrap. Store in the fridge until ready to serve. The pizza will last for a few days but is best served within 2-8 hours.
