The dinner plate is a proposed item, which can turn any Minecraft food into a block, like cake!
This crafting recipe makes a green-ware plate, which is just a clay formation of a plate. It looks like this:
To turn this into a plate, smelt it in a furnace.
You get a complete plate:
Thanks to cerealkiller for the plate pictures!
Once you have a plate, you can put any food on it by right clicking it. From there, you can eat the food at your own pace, so you don't waste any!
Here are some ideas that other users have suggested:
Placing food on plates can be a way to feed animals.
After a plate is used, it probably will get dirty. So wash it in a cauldron before using it again!
Eat with silverware like a civilized human! Maybe THAT could be made of iron!
By popular demand, bowls should be made placeable instead of plates.
Food on plates could be pushed by pistons, and output redstone comparator signals.
For smaller food items, multiple items should fit on one place, for example, cookies and carrots.
Plates are only stackable to 8! Otherwise the tower will topple over!
The amount of hunger food restores stays the same even when on a plate. So if something restores 3 bars, eating one bite will restore one bar and only 2/3 of the food will remain.

Another idea in mind: If you have smaller food items, like cookies or carrots, you should be able to fit multiple of them on one plate!
