Oregano is the spice that gives pizza its characteristic flavor. It is also usually used in chili powder. Oregano tastes great with tomato, egg, or cheese based foods, and is also a great addition to many lamb, pork, and beef main dishes. Try sauteeing aromatic vegetables in olive oil with garlic and Oregano. You can make a savory sauce with melted butter, lemon juice and a bit of Oregano; drizzle it over grilled fish and poultry. An easy way to accent pasta sauces, salad dressings, and ground meat dishes is with a dusting of crushed Oregano leaves.
