A little of this, a little of that, with inspiration from the springtime farmers market: A salsa is more than a red or green sauce drizzled over a taco. Salsas are wonderful mashes of garden herbs, sweet and spicy peppers, aromatics and citrus. Delightfully fresh and usually raw, salsas provide brightness and zing to an assortment of meats, fish, ve g e t abl e s and grains.
