Heat oil in a large skillet over medium-high heat. Sprinkle Italian seasoning on the salmon and put in pan. Cook 3 to 6 minutes on each side or until fish flakes easily when tested with a fork. Remove fish from pan; keep warm.
Add jalapeño and garlic to pan; sauté 5 minutes or until tender. Add tomatoes, capers, olives, wine, and anchovy paste. Sprinkle with parsley. Simmer for 15 minutes or until sauce is thickened.
Return fish to pan and cook until heated through. Serve fish over sauce and with pasta, if desired.
