CHOOSE ONE OR MORE EXTRAS (OPTIONAL):
1 can sliced mushrooms -- (3-ounce) drained
1/4 cup sliced ripe olives
1/4 cup chopped red or green bell pepper
1/4 cup chopped onion
1/4 cup chopped celery
2 garlic cloves -- minced
1 can chopped green chiles -- (4.5-ounce)
1 envelope taco seasoning mix -- (1 1/4-ounce)

CHOOSE ONE OR TWO TOPPINGS:
1/2 cup shredded mozzarella cheese -- (2 ounces)
1/2 cup grated Parmesan cheese
1/2 cup shredded Swiss cheese -- (2 ounces)
1/2 cup fine -- dry breadcrumbs
1 cup round buttery crackers -- crushed
1 cup herb-seasoned stuffing mix

Combine 1 (8-ounce) container sour cream, 1 cup milk, 1 cup water, 1
teaspoon salt, and 1 teaspoon pepper with Sauce Maker (omit sour cream
and milk when using tomatoes). Stir in Vegetable, Pasta/Rice,
Meat/Fish/Poultry, and, if desired, Extras. Spoon into a lightly
greased 13- x 9-inch baking dish.
Bake, covered, at 350F for 1 hour and 10 minutes. Uncover and sprinkle
with Toppings; bake 10 more minutes. Makes 6 servings.

Invent your own one-dish combinations, switching ingredients for
variety. We stirred together the following mixtures and liked the easy
preparation. Each casserole bakes 1 hour and 20 minutes, eliminating
the need to precook the pasta or rice. But don't limit yourself to
these taste-tested recipes -- experiment with different flavors and
create family favorites.
