1 pound hamburger
1 packet taco seasoning mix
1 (8 ounce) jar taco sauce
1 can mushrooms (optional)
2 cups spaghetti sauce
1 pound dry spaghetti
Cheese, shredded
Sour cream
Tortilla chips, crumbled

Brown hamburger; drain. Mix with taco seasoning mix, taco sauce, mushrooms and spaghetti sauce.

Meanwhile, cook spaghetti, then mix into the hamburger mixture. Put into a casserole dish. Sprinkle shredded cheese on top. Cover and bake at 400 degrees F until the cheese is melted.

Spread as much sour cream on top as you desire. Sprinkle cheese and crumbled tortilla chips on top.
