1. Trade meat for hearty legumes. Substitute 1/4 cup of cooked beans, peas, or lentils for each ounce of meat in recipes; try it in tacos, pasta dishes, meat chili, soups, and casseroles.
  2. Redirect savory cravings. That rich flavor you crave is called umami—meaning “savory” in Japanese. Considered the fifth taste, it’s common in meat and fish but can also be found in a variety of vegetarian-friendly sources, including mushrooms, aged cheeses like Parmesan, sweet potatoes, tomatoes, and walnuts.
  3. Reinvent old favorites. Exchange your hamburger patty for a black-bean burger, diced chicken for cubed tofu, and seafood stir-fry for one made with edamame. More from Prevention: 5 Women Who Gave Up Meat and Are Healthier (and Happier) Than Ever
