I know there's sort of another thread on this, but I don't want to hijack it and my situation is kind of different.
I'm allergic to dairy, can't eat gluten, and am sensitive to the hormones in meat and eggs. A lot of soy products also make me sick (specifically soy nuts.. oy) so I try to limit that as well. Also, since I'm stuck eating in a college cafeteria, I'm sort of limited to what I eat (though I'm running for the dining services student committee so hopefully that will change things for all of us at school with celiac disease, food allergies, and food sensitivities!). Most of the vegan/vegetarian foods have some component with gluten in it and the tofu normally is marinaded in soy sauce (which has wheat in it). Sometimes I can get salmon (which I do eat), but Friday-Sunday that's not available and I'd rather not eat it EVERY day. I stuff myself silly with beans for more protein but that doesn't feel healthy either.
That said, I track my food in Fitday and I've only been getting an average of 40 grams of protein a day which really doesn't feel like enough. I'm worried about taking protein powder because I'm insulin resistant and try to cut out ALL sugar out of my diet, but most protein powders are ridiculously high in sugar. Also, I have no real income to speak of (make around $30 a week at a college job) so expensive protein powders are just not feasible.
What are other good, cheap sources of protein that I can add to my diet?

) . The hemp protein has a very low carbohydrate content due to the high fiber content.
I can't imagine how I'd fare without dairy or egg whites!
