"This is a great, very flavorful soup. Good for serving at luncheons or special gatherings with a quiche. To make this soup a little fancier, add 1 cup sliced mushrooms and 1 cup white wine with the onions."
1In a stockpot, melt butter over medium heat. Cook onion in butter until softened. Stir in broccoli, and cover with chicken broth. Simmer until broccoli is tender, 10 to 15 minutes.
2Reduce heat, and stir in cheese cubes until melted. Mix in milk and garlic powder.
3In a small bowl, stir cornstarch into water until dissolved. Stir into soup; cook, stirring frequently, until thick.
