Cut bread into small cubes. Saute onions and celery in margarine until transparent. Combine with bread.
Mix chicken stock, poultry seasoning and pepper together. Add to bread mixture. If mix is too dry, add a bit more stock. Add crab to dressing mix. Flatten chicken breast to 1/4 inch; season with salt and pepper. Spread crab mix on one side of the chicken.
Roll the chicken into a roll and secure with skewers, toothpicks, or string.
Brown in oil, then transfer to a pan. Pour wine over chicken and bake in a 375 oven for 15 – 20 minutes, or until chicken and stuffing are thoroughly cooked.
