If you run out of Italian seasoning, you can replicate the flavors with simple mixes of herbs and spices such as:   ½ teaspoon dried oregano + ½ teaspoon dried basil  ½ teaspoon dried oregano + ¼ teaspoon dried thyme + ¼ teaspoon dried basil  The flavor won’t be exactly the same as if you used a homemade Italian seasoning, but it will be close if you’re in a pinch.
