Savvy meal planning is all about shopping sensibly for groceries. That means enjoying the simplest ingredients as well as the occasional splurges. Real talk: You don’t have to eat with monk-like austerity to be penny-wise. In this luscious spaghetti dish, a modest amount of frozen shrimp gets a lift from affordable clams. The briny juice of the molluscs makes for a rich sauce that doesn’t require a drop of white wine. Apply this same reasoning to other edible extravagances: a drizzle of cold-pressed walnut oil in a vinaigrette, a crumble of exceptional cheese in a salad, flakes of smoked fish in scrambled eggs. When it comes to the finer things in life, measured doses can be extraordinarily satisfying.
