Spray slow cooker with non stick spray. Place chicken on bottom of pot and pour in broth with all seasonings.
Cut cream cheese into small cubes and place on top of meat with the diced bell peppers.
Cover and cook for 4-6 hours (bone-in and/or larger than most will take longer) or until chicken is as tender as you want and cooked thru to the middle. We like it longer so it shreds.
Remove chicken and slice or shred. Into the sauce whisk in cheeses, heavy cream and cornstarch until smooth. Put chicken back into the pot.
Cover and let sit on warm for 15 minutes for sauce to thicken. Then serve over noodles or zoodles cooked separately.
