Although your arteries might disagree, from a rubbish point of view there is no problems fish ‘n chips and pizza as the paper or box can be recycled, composted once shredded, or burned.
For Chinese, Thai, Indian etc take your own container, maybe even reusing one they gave you originally, and pass it over when you order.
Souvalakis, and Subway sandwiches, are good as well, as generally they only come wrapped in paper, and sometimes foil. Although you do need to keep an eye on the servers to make sure they don’t try and slip a plastic bag somewhere. That’s what happened to us when we bought the one pictured below.
Or, my favourite, when you can sit and eat it there.
