  • 3 cup medium noodles (4 oz.)

  • 1 cup chopped celery

  • ¼ cup chopped onion

  • 2 - 3 tablespoon Dijon-style mustard

  1. Preheat oven to 375 degrees F. In large saucepan cook noodles according to package directions. Drain; return noodles to pan.

  2. For sauce, in medium saucepan cook celery and onion in hot butter until tender. Stir in flour, mustard, and 1/4 teaspoon black pepper. Add milk all at once; cook and stir until slightly thickened and bubbly, whisking to remove any lumps.
