Actually, the cottage cheese is good, try tuna in the cottage cheese, you will be suprised. Tofu - well, Im on the fence on that one, some say soy is not good protein. But me being lactose intollerant to a degree. I drink soymilk and have eaten much tofu/seitan/and vegetarian foods. Wildwood soy yogurt rules, Wildwood tofu is tasty. If that is your lifestyle, keep eating it. Try to write out your macronutrient breakdowns, what protein, fat, and carbs are ya eating in a day, how many cals. Take it a step at a time. And it will add up.
Tuna packed in olive oil is tasty too, I have on many occasions taken a can or 3 dump it in a baggie, add some gardenia peppers, mix up, and use lettuce as a wrap.

I vote that tuna is king, well tuna and chicken and beef, and liver, Oh hell I love meats.
