(Using 2 tablespoons flour makes a nice thin gravy. Use more flour if a thicker gravy is required)
Heat olive oil in a saucepan. Whisk first six ingredients together until no longer lumpy. Gradually add mixture to saucepan, stirring frequently. Bring to a boil, reduce heat and simmer until thickened. Add pepper and herbs to taste.
Very good served with a savory loaf, such as the Thanksgiving 'Meat' Loaf found on this site.
