When we think of red meat, we usually mean beef. Yet let's not get stuck on steers. Lamb is also considered a red meat because it's high in myoglobin, a protein in muscle that turns red when combined with oxygen, according to Berkley Wellness Center. Poultry is considered a white meat because it has less myoglobin. So if you're sick of beef, poultry, and seafood, and you are still craving some animal protein, try lamb, which is popular in several parts of Europe, Middle East, Australia, New Zealand, and North Africa. It's a meat approved by several of the world's major religions: Islam, Christianity, and Judaism. For a special occasion like your holiday meals, try a leg of lamb recipe like this one that calls for rubbing the lamb with garlic and lemon, coating it with spices, and cooking it on a rotisserie over potatoes, olives, onions, and fennel.
