Define “healthy” any way you want, I guess. I define it as “if I ate it every day for a year I would be better off at the end.”
I love raspberries and raspberry-flavored anything (even that borderline disgusting raspberry diet coke that you can get at Burger King).
Sometimes my local supermarket has those plastic clamshell boxes of 12 oz. of raspberries for $5*. When I can get one of those, I put the berries in a big bowl and mix in a container of vanilla (Greek) yogurt and maybe a little sugar to balance the tartness. That’s it, simple and gorgeous.
*When I was growing up we did u-pick raspberries and got several crates, which my mother would make jam with. Naturally there was plenty of fresh raspberry eating going on during those few weeks of the season. It was heaven. Now raspberries are expensive and not nearly as good, but still better than anything else.
