In a large pan, heat the extra-virgin olive oil over medium-high to high heat.
Season the chicken liberally with salt, pepper and poultry seasoning. When the oil is hot and ripples, add the chicken and brown for 5 minutes, then turn and sprinkle with rosemary. Cook until the chicken is tender and cooked through, about 5 minutes more.
In a small bowl, stir together the marmalade, vinegar and stock and pour over the chicken. Cook for 2 to 3 minutes or until the sauce has thickened and becomes a thin glaze. Add the scallions during the last minute of cooking time. Arrange on a serving platter and serve topped with arugula greens.
