In a large pot or Dutch oven, add 2 Tbsp oil, chopped onions, shredded carrots, and peppers and sauté on medium high heat for about 3-4 minutes, until tender.
Add cubed chicken and sauté for about 4-5 minutes, until the chicken is cooked. (Season the chicken with salt and pepper, to taste if desired.)
Once the veggies are tender, add minced garlic to the pot and cook for an additional minute, until fragrant. Add ketchup and mix to combine.
Pour in the chicken broth, water, salt, pepper, and Mr. Dash seasoning into the pot and bring it to a boil.
When boiling add the potatoes, millet, and dried mushrooms to the pot and cook on medium heat for 14-15 minutes, until potatoes are tender.
Add chopped cabbage, vinegar, and freshly chopped herbs to the pot and cook for another 3-4 minutes, until cabbage gets tender. (Taste and adjust seasonings for desired taste.)
Remove from heat and ladle into bowls and serve while hot.
