In a large skillet, cook the ground beef over medium heat until browned. Drain excess fat.
Add taco seasoning and 3/4 cup of water. Simmer for 5 minutes.
In a baking dish, layer the ingredients: start with salsa, add noodles, then beef mixture, and cheese. Repeat the layers until you have used all ingredients.
Cover with aluminum foil and bake for 30 minutes. Remove foil and bake for an additional 10 minutes or until cheese is bubbly.
Notes
Feel free to add your favorite toppings like sour cream, guacamole, or jalapeños.
