In a small bowl or small zip-close bag, combine the herbs and spices. Season one side of each sole fillet with 1 teaspoon of seasoning mixture on the top side of the fillet — not the skin side.
Heat a large saute pan on medium-high heat; add olive oil. Cook fillets on the seasoned side first for about 1 minute. Flip the fillets and lower the heat to medium. Cover for about 2 to 3 minutes. Fillets should flake when done. Use a meat thermometer to make sure the internal temperature of the fillet has reached 145 F before serving.
