All you need is a mug or ramekin—and a few minutes—to cook one of these sweet and savory recipes. Because these microwavable meals are mixed, heated, and served in that single dish, there\u2019s little prep time and practically nothing to clean. The 60 \u201cmug cakes,\u201d many of them vegetarian or vegan, include Tomatoes and Capers; Spiced Tofu, Rice, and Walnut; Shrimp and Zucchini; and a yummy Chocolate, Coconut, Raisin and Banana Souffl\u00e9.
