SALMON: Preheat oven to 375 degrees F. Sautee portabellas in olive oil for 3-4 minutes over medium heat until soft, then set aside. Place each salmon fillet on two sheets of phyllo and sprinkle lightly with salt. Divide portabella mix evenly on top of fillets and wrap sheets around each fillet to form packets. Bake packets for 20-25 minutes until phyllo is lightly browned.
SAUCE: Add Pinot Noir to sauce pan and reduce over medium heat by half. Add stock, red pepper puree and thyme. Reduce by another third. Turn off heat, swirl in butter, add salt and pepper to taste and remove thyme. Reheat slowly to a simmer before serving.
To Plate: Spoon warmed sauce evenly over packets and garnish with thyme or mint sprig.
