It took chef Ana Sortun about two and a half years to develop her new food products, Chef Set, but the project’s roots actually go back much further. “I was always that kid on a diet,’’ says Sortun, “My mom would put me on a diet for a couple of weeks, and I’d see everyone having chocolate cake and I’d get a scoop of grapefruit sorbet. It felt like a punishment.’’ Don’t think that her new project has anything to do with a healthy chocolate cake. What Sortun has done is come up with healthy meals in which she provides the grain, seasonings, spices, nuts, and garnishes - “A Fast Way to Slow Food,’’ reads the packaging - and you add salmon or chicken or whatever else the main course calls for. Each stylish box contains three packets with instructions for how to cook the grain, and roast or saute the protein.
