In a medium saucepan, bring just to a boil: 1 ⅓ cups water, 2/3 cup milk and 2 tbsp margarine. Reduce heat to medium.

Slowly stir in pasta, Special Seasonings, asparagus, squash and onions. Separate pasta with a fork, if needed. Return to a boil. Boil uncovered 4 to 5 minutes or until pasta is tender, stirring frequently. Add salmon and mustard; cook and stir until heated through.

Sauce will be thin. Let stand 5 minutes to thicken. Stir in basil before serving, if desired.
