put meat, hash brown, onion and cheese in a greased slow cooker.. then mix soup, milk, sour cream together… I add things like salt and pepper, minced garlic, onion powder to the mixture if you want. then pour over kielbasa etc. then sprinkle about 1/2 cup more cheese on top.. cook on low for 6 hours or high for about 3-4 hours.. serve with salad, or roasted veggies for a complete meal… if your feeling super fatty, then serve with Texas garlic toast
