My selection here in Canada is a bit limited, but I really like Gardein and Field Roast brands. Gardein makes all kinds of things -- burgers, ground "beef," meatballs, chicken and fish alternatives. Looking at their
website they also make some convenience foods like vegan pizza pockets and skillet meals.
Field Roast makes a lot of things too; I've only tried their sausages and burgers but they are both excellent. Because they are seitan-based the Field Roast items are higher in protein than a lot of other options. It looks like they offer a wider selection in the US than they do here, and I would gamble on anything made by them at this point. They also produce a variety of vegan cheeses that are pretty solid.
I've eaten the Sol Cuisine burgers in the past and they are quite good. Yves brand is hit and miss.
Quorn products were mentioned earlier but I haven't tried them. I hear
Beyond Burger is great and the closest thing there is to an actual beef burger, but I haven't had a chance to try it.
Also that Very Good Butchers
meat club I mentioned earlier does ship to the States. I imagine there are similar services closer to home, too.
Youtube is full of vegan channels,
The Vegan Zombie is one I like and he does a lot of "taste test" videos that might give you some ideas for what you'd want to try.
