Harvest Moon Grille — the orange gourmet food truck owned by Grateful Growers Farm — has been parked near Johnson & Wales University every Monday and Wednesday since the beginning of December. On their opening day, I released my Intro to Food Writing class (I also teach at J&W) so students could buy one of their marvelous pork sandwiches. Their menu changes weekly, but the best I had this week was their Three Little Piggies Pasta with pancetta, country ham, and smoked ham (from animals raised on their farm and products cured there as well) bathed in a garlic cream sauce with slivers of green peppers and mushrooms over an organic penne. All this for $6.
