What could be simpler than tossing fresh ingredients in the skillet to make a mouthwatering meal? On a busy weeknight, nothing beats it for ease of preparation and quick clean-up. "Good Housekeeping" presents more than 115 tantalizing and varied one-dish recipes for meat, poultry, vegetables, seafood, eggs, and cheese. And there's something for every occasion. Do the kids want comfort food? No problem: try Lasagna tossed with Spinach and Ricotta. Unexpected company dropping by? Impress them with Couscous Paella or Tuscan Steak and Beans. And to help you choose just the right equipment, Susan Westmoreland, "Good Housekeeping'"s Food Director and a trained chef, offers advice on her favorite skillets.
