Looking for lean protein options

While reviewing my diary I noticed I have more carbs than anything followed by fat and very little protein. I really want to try and increase the amount of protein in my diet but am having a hard time coming up with food that is lean with a lot of protein, especially snack ideas. Please keep in mind that I am striving for an organic non gmo lifestyle so I don't eat much dairy since its so expensive for me, and I like to stay away from lunch meat. The only thing that comes to mind is eggs! I'm stumped, can anyone thing of other lean protien, preferably for snacks? Thanks
