Cooking with Blockheads is a cure little mod. There are many mods that add food, Pam's Harvestcraft for example, but most of these are just made through a crafting table or a furnace. It'd be a nice change of pace to make you actually need to, and benefit from, using the kitchen from Cooking with Blockheads.
Some stuff needs to be tested, e.g. how well the blocks can be automated. If they're not particularly well suited for it, talking with the developer or creating recipes for autocrafting (available late-midgame or lategame perhaps) may be worth it.
