Preheat the oven to 350°F (175°C).
In a large skillet over medium‑high heat, brown the ground beef until no pink remains, then drain excess fat.
Return the beef to the skillet and add the seasoned salt, taco seasoning, undrained diced tomatoes, tomato sauce, and chopped green chilies; reduce heat and simmer uncovered for 15–20 minutes.
Meanwhile, in a small bowl whisk the lightly beaten eggs together with the cottage cheese until blended.
Grease an 11×7 baking dish. Layer half of the meat sauce in the dish, then half of the torn corn tortillas, half of the cottage cheese‑egg mixture, and half of the shredded cheese.
Repeat the layers with the remaining meat sauce, tortillas, cottage cheese mixture, and shredded cheese.
Bake uncovered at 350°F (175°C) for about 30 minutes, or until the casserole is bubbly and the cheese is melted.
Let the lasagna stand for 5 minutes, then top with broken tortilla chips, diced tomatoes, avocado chunks, and salsa before serving.
