1In 1-quart saucepan, heat mushrooms, wine, tomato paste, tomato, onion, garlic and half of the thyme to boiling; reduce heat to medium. Cook about 5 minutes, stirring occasionally, until slightly thickened.
2Meanwhile, sprinkle salt and remaining thyme over fish fillets; roll up fillets. In 8-inch nonstick skillet, heat oil over medium-high heat. Cook rolled fish, seam side down, in oil 4 to 5 minutes, turning as needed, until lightly browned on all sides.
3Top fish with tomato mixture; reduce heat to low. Cover; cook 5 minutes longer or until fish flakes easily with fork.
