The expression "on the back burner" means to put something temporarily aside or delay it for a later time or when it is more convenient. It comes from the idea of putting a pot on the back burner of a stove, where it will cook more slowly than on the front burner. So, when someone says they have put a project "on the back burner," they mean they have paused or postponed it for the time being in favor of other more pressing matters.
