You may think a health food market's prepared-foods counter would feature 25 different tofu casseroles and some sprouts-n-avocado sandwiches. Not here. Yes, you'll find vegetarian staples such as spinach sautéed with sesame seeds, beets simmered in orange and ginger, luscious tofu steaks marinated in a mustardy Thai sauce, several varieties of pasta salads. But if you're a carnivore you'll be happy, too. Pick from grilled chicken breasts, spicy Thai chicken curry, stuffed chicken breasts, turkey piccata. Seafoods abound as well: mussels scampi on special during a recent visit, grilled salmon steak, baked trout. There is usually a wide variety of sandwiches depending on how close to lunch you arrive. Back in the refrigerated section you can find some great soups and dips. And just down the counter a dessert awaits: a slice of cake or pie, perhaps, or cookies, tarts, muffins, rolls. If you can't wait to feast, stop outside at a sidewalk table.
