Healthy prepared meal services are taking off in the U.S. and U.K.
It turns out, there are two businesses named Kettlebell Kitchen. The U.S.-based business I found on Google and another out of the U.K. which is the one the article references. Both businesses specialize in healthy meal preparation in their respective countries. In addition, they each seem to have a substantial following and are well-received. It's quite a strange coincidence indeed.
