There are two different issues that you bring up: One is an issue of creating specific protein(s), and the other is creating "meat". "Meat" is really a culinary term, not a scientific one, and describes animal muscle, which is often cooked. There is no way that a plant is going to produce animal muscle and still be a "plant". As far as a plant producing specific proteins, that seems possible in theory, but extremely difficult in practice.
