Cowboy Lasagna

I'm not sure where this recipe originated from but I got it through a yahoo group I was on a long time ago called Casseroles & Crock-pots. This recipe was different and good, It was saved to repeat someday in the future :)

Cowboy Lasagna

2 pounds ground beef
1 (6 ounce) can chopped black olives
1 (4.5 ounce) can mushrooms, drained
1 onion, chopped
1 (16 ounce) jar spaghetti sauce
9 lasagna noodles, cooked and drained
1 1/4 cups frozen corn kernels
1 1/4 cups frozen green peas
8 ounces shredded mozzarella cheese
1 pinch ground black pepper
1 pinch dried oregano
1 dash Italian seasoning

Preheat oven to 350 degrees F (175 degrees) C. Spray a 9x13 pan with
cooking spray. Brown beef in a skillet over medium heat and drain
excess grease. Add the olives, mushrooms, and onion. Stir and cook
until the onions are soft. Stir in the spaghetti sauce, pepper,
oregano, and Italian seasoning. In a small bowl combine the peas and corn.
To assemble, lay 3 noodles on bottom of prepared pan, then one half of
the beef mixture, half of the corn and pea mixture. Repeat. End the
layers with the remaining noodles. Bake in the preheated oven for 25
minutes. Sprinkle the top with cheese and bake for an additional 5
minutes. Let stand 10 minutes before serving.
