2 cups chopped cauliflower (about 1/2 a medium head), steamed
Directions
In a medium saucepan, combine milk, cream cheese, flour, salt, pepper, garlic powder and cayenne, if desired. Cook over medium-high heat, stirring, until mixture comes to a slow boil, 5 to 7 minutes. Remove pan from heat; stir in remaining cheeses and mustard until cheese melts. In a bowl, toss pasta with cauliflower; pour cheese mixture over top; stir. Divide pasta evenly among 7 bowls; serve immediately.
