Baked Taco Spaghetti

Preheat the oven to 350 degrees F. Grease a 2-quart baking dish.

Bring a pan of salted water to a boil over medium-high heat. Add the pasta and cook until al dente. Drain well.

Meanwhile, combine the ground beef and onion in a large skillet over medium-high heat. Cook, stirring frequently, until the meat is no longer pink. Drain off any excess grease.

Stir the taco seasoning mix into the meat mixture. Slowly stir in the water and mix well. Bring the mixture to a boil then reduce the heat to a low simmer. Cook, stirring occasionally, for 2 minutes or until the liquid begins to thicken.

Stir the cooked pasta, corn, 1/2 cup of the cheese, the olives, salsa, and green chiles into the meat. Transfer the pasta mixture to the greased baking dish. Cover the dish with foil and place in the oven. Bake at 350 degrees F for 20-25 minutes or until heated through and bubbly in the center.

Remove the dish from the oven. Sprinkle the top of the meat mixture with the remaining cheese. Sprinkle the cheese layer with shredded lettuce and diced tomato.

Serve immediately.
