Add the chicken stock, stir in the mac and cheese. Add the velveeta, parmesan and cream cheeses. Stir occasionally until all are melted and mixed thoroughly. Add the heavy cream (or milk) and stir till heated through. Remove from the heat, add salt and pepper to taste. Serve. Garnish with smoked paprika and/or parsley. If you add in some left over protein (beans, chicken, pork, etc) and a veggie (broccoli, carrots, peas, etc) – then you have a complete meal in one bowl!
