Preheat oven to 350°F. Spray a loaf pan with cooking spray.
In a large bowl, add ground beef, tortillas, cheese, ⅔ cup salsa, eggs, taco seasoning and green chilies. With your clean hands, combine the mixture until everything is mixed together well.
Add meat to a loaf pan. Place on a baking sheet and put in the oven for 1 to 1 hour 10 minutes, or until meat is cooked. Use a meat thermometer to check.
Remove from oven and let cool for a few minutes before flipping over onto a serving platter. Spread ½ cup salsa and green onions on top. Serve hot.
