Well, obviously more bread would be OP. But here in Industrialcraft we like to improve on the primitive life we are usually stuck with in Minecraft. So, instead of that sucky peasant-bread, why don't we have some sort of way to use those tasty wheats to make some high effectiveness super-bread? Perhaps 3 flour, 1 bucket of water,& 1 egg.
But why stop there, when we have so many item ID's to fill?
How about some sort of combined lunch, 1 super-bread, 1 apple, 1 steak/porkchop/fish/chicken, and 1 seeds (sprouts, bro) makes a delicious pack lunch that restores 6 food, and provides 5 hearts of healing instantly! Of course, this bad boy can't be canned, because his purpose is to provide you an extremely dense, high calorie meal that can be kept in mass quantities for super long exploratory voyages.
I mean, if you REALLY wanted to go all-out, you could make the crafting totally open-ended. I bet the pixel artists would be nuts for making a thousand different foods in 16x16 pixel art. (XD)
