Can you identify this sci-fi book for me?

I remember reading a book (a series?) when I was a kid during the late 70s. I remember almost nothing about it other than the spaceship had a 'food replicator' that you only had to think about the food you wanted and it would be produced. However, as a result of someone in the family thinking too hard about their food in the past, it would now only produce beans on toast or something.

Any thoughts?
