One man's nut is another man's meal

You might not see a nut as an appetizing meal but another person who is really hungry can see that nut as a full course meal and make use of it.
It means that you should appreciate every nut that hits your stomach.

Person 1: Look at this sandwich... gross! Would you eat it if i gave it to you?
Person 2: Well, I am really hungry.
Person 1: I can't believe it! I guess one man's nut is another man's meal.
