Fair question. It probably has to do with perspective. For some it means no gluten, or no carbs, or no . . . For me, I THINK it means no added weird chemicals (that have no health value), no excessive sugar/salt/fake-fat. For you, it may rightly mean something else.
However, I think we all have a sense of what is “healthy” for us (if we’re honest). But far be it for me to speak for others. So I’ll go with with simply . . . natural, old-school, mostly veggie and preferably local.
So how does one travel on the road, with kids, and limited time to eat? Stay tuned . . .
