Animal meat restores 50% of satiety when grilled and eaten. It's a 1 to 1 craft. Pumpkins on the other hand also when grilled restore 50% of satiety and they are a 1 to 4 craft.
Not sure if this is by design or an oversight but no other craft I saw there for food was more than 1 to 1. Not that I'll complain as Pumpkins in real life are pretty big and if wolves weren't so easy to come by I'd do more pumpkin gathering as they are the most efficient food source in the game thus far.
The problem with Pumpkins, for efficiency purposes, is that it is one of the only foods that doesn't stack when uncooked. I guess to compensate for that, when you do cook it, you get a 4 for 1 return
