Step 1

Preheat the oven to 350 degrees Fahrenheit (175°C) and lightly grease a 9x13 baking dish with cooking spray.

Step 2

In a large skillet, brown the ground beef over medium heat. If there appears to be a lot of excess moisture, carefully drain some away. A little grease is OK, as it adds flavor.

Step 3

Then add the beans, chiles, taco seasoning, and hot salsa.

Step 4

Stir until well combined, then spoon about 1/3 of the mixture into the baking dish, spreading it evenly over the bottom.

Step 5

Sprinkle 1 cup of cheese over the meat, then add a layer of pasta noodles.

Step 6

Repeat twice, using the remaining meat, noodles, and sauce.

Step 7

Mix the water and mild salsa in a small bowl, then pour it over the layered lasagna. (Do not add water if using cooked lasagna noodles.)

Step 8

Cover the dish with foil and bake for one hour.

Step 9

Remove the dish from the oven, remove the foil, then top the lasagna with sour cream, onions, black olives, and tomatoes.

Step 10

Sprinkle on the remaining 1 cup of cheese, and bake uncovered for five more minutes.

Step 11

Once the cheese is melted and bubbly, remove the dish from the oven and let the lasagna rest for 10-15 minutes before serving.

Step 12

Top with taco fixings, and enjoy!
