In a saucepan, simmer the butter until bubbling and add the chicken. Cook until done. Regular breasts can be 5 min. each side, cutlets may only take 1 to 2 min each side.
While the chicken is cooking, in a separate bowl combine the capers, lemon juice and wine. If you like a lot of sauce, double these ingredients. Once the chicken is browned on both sides, add the sauce to the pan and cook down for another 3 min. or so. Goes well with rice and asparagus.
