I combined 3 separate recipes from my Croatian heritage to come up with this Americanized version.
From my food blog at: http://www.comfortcookadventures.com/2013/07/doesnt-matter-what-language-you-speak.html
Set a 6 quart crock pot on high; spray inside with nonstick cooking spray.
Begin layering ingredients inside – tomatoes, onion, bell pepper, ¼ cup flour sprinkled evenly over all, 1 tablespoon garlic. Place in the chicken breast pieces and spread the remaining ¼ cup of flour over them. Add the mushrooms, remaining garlic; then evenly sprinkle over the black pepper and paprika. Pour the stock and white wine over the top.
Cover and cook for 3 and ½ hours; remove chicken and 1/4 of the vegetables. Use a stand or immersion blender to puree the remaining vegetables, and thicken the liquid. Return the chicken and reserved vegetables to the pot; cover and cook for another half hour before serving. Also during that last half hour, prepare the pasta to desired tenderness; place a serving into bowl and top with sauce, chicken and some vegetables.
