1Heat oven to 400°F, lightly oil a small roasting pan.
2In medium-size bowl, combine apple, carrot, green onion, lemon juice, ginger, mustard, salt, pepper, and thyme; mix well.
3Spread one-quarter of apple mixture evenly over length of each fillet; carefully roll up to enclose apple filling. Place stuffed fillets, seam side down, in oiled pan. Pour broth over rolled fillets, cover with aluminum foil and bake 10 to 15 minutes, or until fish is opaque and barely flakes. Serve.
