Step 1

Preheat oven to 400°F with oven rack in top third of oven. Heat oil in a large skillet over medium-high. Add onion and garlic; cook, stirring often, until translucent, about 4 minutes. Add ground beef, chili powder, cumin, oregano, and paprika, and cook, stirring often, until beef is no longer pink, about 6 minutes. Stir in salsa, taco sauce, and broth; cook, stirring often, until slightly thickened, about 3 minutes. Stir in beans and cilantro.

Step 2

Lightly coat a 13- x 9-inch, 3-quart baking dish with cooking spray. Spread one-third of the chips (about 2 cups) on bottom. Top with half of the beef mixture (about 3 cups). Spread another layer of tortilla chips over beef, and sprinkle with 1 1/2 cups of the cheese. Top with remaining half of beef mixture, and sprinkle with remaining chips and cheese. Cover with aluminum foil, and bake in preheated oven until mixture is starting to bubble around the edges, 15 to 20 minutes.

Step 3

Uncover and continue to bake until lightly browned and bubbly, about 5 more minutes. Garnish with chopped cilantro.
