Como dizer "aproximadamente" em inglês

Hi guys,

I know many ways to say "mais ou menos": so so, approximately, about, etc.

However, a few days ago I saw myself without an answer to a simple question. How could I say "que horas você come mais ou menos?". The rest of phrase I guess is "what time do you eat ...?", but I can't find a good "mais ou menos" option to fill out this question.

Any idea?

Thanks!
