Place a 2-quart saucepan over medium heat. Add the water, milk, chicken bouillon cubes, butter, pasta, garlic powder, parsley, and pepper. Bring to a boil then turn the heat down to a simmer. Cook, uncovered, for 15 minutes or until the pasta is tender. Remove the pan from the heat and place a cover on it. Let it sit for 5 minutes for the sauce to thicken a bit more. Stir before serving. Variations: add 1 cup chopped cooked chicken, turkey, drained tuna or other meat. Make it into stroganoff by adding browned and drained ground beef and using beef bouillon cubes instead of chicken and stirring in 1/4 cup sour cream before serving.
