Preheat your oven to 350 degrees Fahrenheit.
Take an oven-friendly skillet and heat it over medium-high temperature on your stove. Add ground beef and onions to the skillet. Continue sautéing until the beef turns brown and the onions become soft.
Now, introduce the taco seasoning, green chilis, and cream cheese to the skillet. Keep sautéing until the cream cheese melts fully and blends well with the mixture.
After that, layer the mixture evenly with corn chips, followed by a generous sprinkling of shredded cheese.
Place the skillet in the preheated oven and bake for about 20 minutes.
After baking, remove the skillet carefully from the oven. Garnish the dish with fresh, shredded lettuce and chopped tomato.
Serve hot and for an extra flavor punch, add salsa and sour cream as per your preference. Enjoy your delightful Stroll-Through Taco Bake!
