     1/8  teaspoon      ground white pepper
   2      pounds        boneless skinless turkey breast
   3      tablespoons   all-purpose flour
     1/3  cup           dry white wine or chicken broth

Preparation:

In a 3-quart or large electric slow cooker, combine onion, garlic, mushrooms, thyme, and white pepper. Rinse turkey, pat dry and cut into 1 1/2-inch cubes. Coat turkey cubes with flour; arrange on top of onion mixture. Mix wine and tomato paste; pour over turkey. Cover and cook at low setting until turkey is very tender when pierced ( 7 1/2 to 8 1/2 hours). Stir gently to coat turkey with sauce, then season to taste with salt.
