1/4 cup sour cream, thinned with a couple teaspoons of milk if you want to drizzle it!
1 cup chopped iceberg lettuce
Instructions
Preheat oven to 375.
Heat a medium sized skillet over medium-high heat and saute the beef and onion together until the meat is no longer pink. Stir in the taco sauce and set aside.
Scatter half of the tortilla chips in the bottom of an oven-proof pie plate and spoon the meat mixture over the chips.
Bake until the cheese is melted, about 10 minutes.
Remove from oven and top with tomatoes, then avocado, then sour cream, then remaining chips, then lettuce.
Serve at once, scooping all the way to the bottom to get a bite of everything!
