Feeding chickens with seeds, instead of wheat. Much, much higher spawn rate of chickens from eggs, but chickens need to be fed to start laying eggs for a minecraft day, instead of doing it at all times.
Boiled eggs for 1 food with high saturation!
Pumpkin stew!
Naturally grown Pumpkins without a face on them, and a pumpkin->carved pumpkin recipe.
Moar Potions! (Increased armour value, water breathing, faster swimming, feather falling, 'spines' that deal damage to attackers for a while..)
