You can always get meat patties from McDonalds? They are pretty much just beef and salt. Get just patties, or a burger with as many extra patties as they will let you have (with no extras) and throw the bun in the bin.
I bet they use trash oil, but it may be a good source of food in desperation (rather than something battered or coated and fried) and probably a whole lot better than processed meat and milk..
We have places in Australia that do roast meat in a roll. In desperation we will eat there and ask for just a plate of roast meat. We pay more for it, but I think it is better to pay and be healthy.
