Lentils!

For all you health buffs out there, I present to you; the lentil. A natural source of protein, this sucker packs 26g of protein per 100g serving. These things are good to cook in soup or to have by itself with salt, pepper and a bit of butter.

Word of advice: best to soak these in water for 4-7 hours before cooking, If you don't, you'll most likely get some type of stomach problem. Good luck guys!
