My Lunches Are Very Interesting

I eat fairly light lunches. It usually consists of a tuna sandwich, baby carrots, a cheese wheel and a pickle, topped off by a yummy low-fat brownie. The tuna is usually the only protein I get in the day because I don't eat much meat- I eat mostly vegetables. I prefer the tuna to turkey sandwiches because if I don't buy the right deli turkey the sulfates give me a headache and egg salad sandwiches because I really need to be in the mood for egg salad or it makes me want to gag. So tuna is my top choice. But I'm going to have eat much less tuna or stop entirely because I found out tuna fish are being eaten into extinction and I don't want to be a part of it. And I'm sad. Maybe I can get it as a treat?
