Jan Brett's website also has some great ideas and printables for a gingerbread unit, including masks for each of the characters and a printable game board.

After reading the more traditional Gingerbread Man stories, you can read some of the other versions, like The Runaway Tortilla by Eric Kimmel and The Stinky Cheese Man. Even my PreK students have enjoyed reading these stories and have been able to do Venn diagram comparisons.
Does anyone have a recipe for the cinnamon applesauce ornaments?
