The inputs into meat today are things like soy and feed corn, which aren't particularly good for people. It's not quite as easy as just not eating meat. Many of the farms need to switch to other crops that are healthy which requires different machines, more labor, or other factors. You probably aren't going to see too much drop in other food prices since much of the cost of foods (especially corn and soy related) is in the processing and distribution, not in the actual growing. Then you need to convince people they want to eat whatever the new product is. You could give people something made from scraps similar to dog food, but that's not going to go over well for a bunch of reasons.
