Yummy super low fat foods?

I recently had to go to the ER because a thing happened and basically, I can avoid gallstones and losing my gallbladder if I avoid fat. No problem, I say! I get rid of the infection, 3 day hospital stay, a week liquid diet, and now I realise how hard it is to find low fat stuff!
I've been living of sherbert, otter pops, Gatorade, sodas and sandwiches with mustard, pickles, black olives and turkey. I NEED TO FIND REAL FOOD. I can't live like this I was raised on steamed vegetables and steak and potatoes.
I need to find some good food that doesn't cost a lot and has 0-5g of fat per serving. I can't eat white flour, tropical oils, dairy products except fat free milk etc.


Any ideas for fat-free stuff i can eat for the rest of my life?
