Taco spaghetti supreme

Ingredients:

8 ounces spaghetti, broken
1 1/2 pounds lean ground beef
1 large onion, chopped (1 cup)
1 cup water
1 (1 1/4 ounce) envelope taco seasoning mix
1 (2 1/2 ounce) can sliced pitted ripe olives
1 (16 ounce) jar thick and chunky-style salsa (mild or medium)
2 cups shredded Cheddar cheese (8 ounce)

Preparation:

Cook pasta according to package directions. Drain pasta and rinse with cold water. Drain again.
In a 12-inch skillet, cook ground beef and onion until meat is brown. Drain off fat.
Stir in 1 cup water and 1 package of taco seasoning mix. Bring to a boil, then reduce heat.
Simmer, uncovered, for about 2 minutes, stirring occasionally.
Stir in cooked pasta, olives, half the shredded cheese and salsa. Simmer another 5 minutes.
Transfer mixture to a lightly greased 2-quart round casserole.
Cover and bake at 350 degrees F for 15 to 20 minutes or until heated through.
Sprinkle with remaining cheese.
