Terrific Tuna Tetrazzini

TERRIFIC TUNA TETRAZZINI

1 can (6 oz.) tuna, drained
¼ lb. Spaghetti
1 c. frozen peas
1 c. sour cream
½ t. prepared mustard
1 c. grated mozzarella cheese
Pinch white pepper, optional

Preheat oven to 375ºF . Bring a large pot of salted water to a full rolling boil. Add the spaghetti and boil uncovered, stirring occasionally, until cooked al dente, about 8 to 10 minutes. Then, drain but do not rinse. Meanwhile, rinse the peas under running water to remove the ice crystals. Drain well and set aside. In a large bowl, stir the sour cream with the mustard and sherry, if using. Add the drained cooked spaghetti and stir until coated. Then stir in ½ cup mozzarella cheese. Add the tuna and peas. Stir just until evenly distributed. Taste and add more mustard or some white pepper, if you wish. Turn the tuna mixture into a deep-dish pie plate. Sprinkle with the remaining cheese. Bake in the center of the preheated oven until hot, about 25 minutes.
