Chicken à la Stanley

Melt one-fourth cup butter, add one large onion thinly sliced, and two broilers cut in pieces for serving; cover, and cook slowly ten minutes; then add one cup Chicken Stock, and cook until meat is tender. Remove chickens, rub stock and onions through a sieve, and add one and one-half tablespoons each butter and flour cooked together. Add cream to make sauce of the right consistency. Season with salt and pepper. Arrange chicken on serving dish, pour around sauce, and garnish dish with bananas cut in diagonal slices dipped in flour and sautéd in butter.
