It would likely be about 8 hours on low, or 2 hours on high and 2.5 – 3 hours on low.
Put more Mrs. Dash on once or twice through the cooking process.
Add the vegetables for the last hour. Definitely no longer as they’d get too mush. Around the same time, put a spoon or two of butter (or margarine) on the potato level.
Spread bbq sauce on half of your chicken pieces for the final 2 – 3 hours. You can taste them with and without sauce and decide how you like them. You can also use the unsauced ones to make nice chicken sandwiches.
This probably sounds weird, but I’d take one of those hot dogs, dice it into tiny pieces and throw it in with the potatoes if you’re using water instead of broth. It will add flavour to the cooking liquid. It’s up to you whether or not you actually eat those tiny hot dogs pieces at the end.
