Preheat your oven to 350°F. Lightly grease a 9-inch pie dish with cooking spray.

In a skillet over medium heat, cook the ground beef until no longer pink. Drain excess grease.

Stir in taco seasoning and salsa into the beef, and simmer for a couple of minutes until the mixture thickens slightly.

Unroll the crescent dough and press it into the bottom and up the sides of the pie dish, sealing any perforations.

Evenly spread the beef mixture over the crescent dough crust.

Sprinkle the crushed tortilla chips on top of the beef layer.

Spread sour cream over the tortilla chips, and then sprinkle the shredded cheddar cheese on top.

Bake for 20-25 minutes, or until the edges of the dough are golden brown and the cheese is bubbly.

Let the taco pie cool for a few minutes before slicing. Serve with optional toppings as desired.
