Half-Eaten Food

Petercat

A pizza with bites taken out of it, maybe half a pizza on the plate and two or three bitten slices. A crust.
Sandwiches. There are a couple, but can't use them in every dining scene.
Steaks with separate chunks to place on a fork. Baked potato, same.
Used napkins. Messy clothing works somewhat if you scale it down and retexture, but original would be nice.
Bitten-into fried chicken, and every artist's staple, Ramen on a fork, crackers and cheese. Or sardines.

There are more possibilities, but I'd be happy to have those.
