Bacon, Mac and Cheese Soup

In large pot, cook bacon until crisp; drain on paper towels. Drain all but 1 tablespoon bacon drippings from the pot. Cook and stir onion in drippings until crisp-tender, about 4 to 5 minutes. Add macaroni, cheese sauce mix, and milk to the pot and bring to a boil. Reduce heat and simmer for 8 minutes, stirring frequently. Then add peas and Parmesan cheese; cook, stirring, until peas are hot and cheese is melted, about 4 minutes. Top with bacon and serve. Serves 4
