Add sour cream to the dough, make sure you use enough, so the pizza won't be dry.
Season with salt and pepper.
Cut the pumpkin (I had butternut) into sticks and add to the pizza.
Add the pine nuts, rosemary, onions (cut in rings) and vegan cheese on top.
Bake for 25-30 minutes, keep an eye on it.
You can brush it with some olive oil in between, so the pumpkin won't get too dry.
Enjoy warm :-)
