Personally, we could (and obviously do!) quite happily eat the same thing for dinner for a week straight. If the leftovers last longer than that, we definitely start to get a little bored, but luckily that doesn't happen very often.
It's slightly different for breakfast and lunch. For those meals, we tend to go through phases of eating one particular kind of meal - like yogurt with granola or pasta salads. We can eat these basic meals with very little variation for weeks before we get fed up and need to find a replacement.
What about you?
