Crockpot Recipe: Unknown Chicken but one of the Best I've had

Someone made this chicken with ketchup dish for me one and I thought it wouuld be awful (chicken and ketchup??) but it was one of the tastiest chicken dishes ever. Cooking in a crockpot (slow cooker) makes the chicken more moist and the sauce even tastier because of the long simmer.

2 garlic cloves, minced
1 onion, sliced
2 C Heinz ketchup
2 bay leaves
salt & pepper
2 T vinegar
2 c water
1 T oil
1 C carrots, sliced .
4 T fresh parsley, sliced .
2-2 1/2 C chicken breasts .
2 T salt
Directions

1. In a frying pan brown the chicken in oil.
Sprinkle with salt & pepper.
Once browned, remove.
Put into crock pot.
Using the same frying pan, garlic, saute the onion, carrots & parsley until lightly browned.
Put in crock pot.
Add the remaining ingredients.
Stir this to mix together.
Cover.
Cook on high for 4 hrs, low 7/8 hrs.
