I mostly agree with you about the looking bad and not tasting good, but I have made the “Meat Hand” before and that was just as good as normal food if you like meatloaf. Just make your recipe of choice but form into a hand shape, top it with a little cheese before baking, and cook on a sheet pan, then transfer into mashed taters. Looks great/horrifying, hard to mess up, and tastes like regular food. Plus ketchup makes “blood.”. Options fingernails are just onion slivers and the wrist is the onion core/center part.
Pic below isn’t mine, but mine came out looking just as good.
