Combine all of the quail marinade ingredients except oil and butter. Add the quail and marinate for at least 3 hours in the refrigerator. Remove the quail from the marinade and saute in olive oil and butter. Cook for 2 to 4 minutes on each side. They will turn a golden dark oak color.
Combine the lettuce, spring mix, tomato, onion, and cilantro in a large bowl. Dress the salad with dressing. Divide salad onto 4 salad plates. Cut the quail in 1/2 and place at the base of the salad. Garnish with chives or scallions and serve.
