Salmon
Brush the salmon fillets with oil and broil (or grill) until cooked through (about 3 minutes per side).
While the salmon is cooking, prepare the Orange Butter sauce (recipe follows).
Orange Butter Sauce
Place the vinegar, white wine and minced white parts of green onions in a small saucepan. Bring to a boil, then reduce heat to medium and slowly boil the mixture until liquid is reduced to about 1 tablespoon (2-3 minutes). Reduce heat to low, then slowly whisk in the butter, piece by piece until melted. Add chives, basil (or marjoram) and orange zest. Season cayenne pepper and salt to taste.
Spoon equal amounts of the sauce over each salmon fillet and serve immediately. Serve with orange slices, if desired.
