Mock Meat: Where's the beef?

Butcher shops are becoming scarcer but there's a new breed sharpening their knives to slice a different kind of meat - made from plants. ''Vegetarian butchers" are popping up across the globe, selling products that mimic meat but contain no animal flesh . Their counters are brimming with chicken, ham, meatballs, minced beef, steak - even seafood - that looks, feels and tastes like the real deal, but are made from plant protein.
