That’s actually pretty clever.
Here’s what I think he did:
The food was already on the plate when the main footage was shot, and he drops the package behind the table (on the chair, likely).
Then it was edited to remove the food at the beginning as well as to change the dropping package into the spaghetti.
Possibly another piece of footage with the spaghetti falling was used, which would have been done as the first shot so it lands in the same place, but you should also be able to do it by cutting out the spaghetti from a still image of it’s beginning position on the plate and mesh warping it.
