You can, but most vegetarians, especially vegans suffer from malnutrition because they don't eat enough from plant sources. As I stated, you have to eat alot of beans and nuts. Tofu as well.

Well Gandalf, you claim to know about that already, but obviously you are doing something wrong. You either aren't eating enough, or you are aren't giving parts of your muscles proper rest. You have to consistantly eat meals, at least 6 times a day. It's pretty tough to do, but once you get use to it, you'll be big in no time.

I'm a of a thin-body type as well, and believe me you can get bigger. In 3 months, I went from a post-surgical weight of 153 to 165 while maintaining a 7% BF. It required eating a ton of healthy food, and not one bit of shit. In my first years of working out it took me a year to gain 12 pounds of muscle, because I kept screwed up without and assumed I knew everything just because I learned a lot of exercises.

Read some articles on bodybuilding.com to self-assess what you aren't doing right. You can't assume you know that, there's always something to learn about exercise, learning doesn't stop. The more you learn, the better you'll be at gaining that mass.
