[serious] Where do I get my protein?

I've been eating a plant-based diet for over a year, so I'm rolling my eyes as much as you. BUT I've recently started lifting, and I supposedly need something like 60g of protein a day.

A cup of lentils is only 18g, and I think that's the best I've come up with so far (also trying to keep calories low). Do I need to add Vega powder to my diet? What do other lifters do?
