Quinoa, if you can stomach it. It's supposed to have most of the amino acids.
Beans + rice.
As for lentils, I bring 'em to a boil, then cook for 12-14 min. Drain, then stir them into a vinaigrette of lime juice & toasted sesame oil. I'll add a goodly amount of ground cumin, along with salt, pepper & some chipotle powder. Grated carrot & chopped cilantro finish it off.
Quick, 'n easy, but I'd not want it passing over my head...
