In medium saucepan, bring 2 cups water and 2 Tbsp. margarine to a boil. Slowly stir in pasta. Return to a boil.

Reduce heat to medium. Boil uncovered, 12-14 minutes or until most of water is absorbed, stirring frequently.

Stir in 2/3 cup milk, Special Seasonings and 2 cans (5 oz. each) tuna, drained, broken into chunks. Return to a boil; cook 1-2 min. or until pasta is just tender. Sauce will be thin. Let stand 3-5 min. to thicken.
