Notes
For the Upchuckin' Pumpkin presentation, I carved a small pumpkin with his mouth open and eyes closed and placed it on the platter. Then I spread the pasta salad around it, including some in the mouth of the pumpkin to make it look like it's puking {ewww!}. A gross out presentation that is great for a Halloween party!
