Step 1

Preheat oven to 400°F. Heat oil in a large nonstick skillet over medium-high. Add onion, bell pepper, and jalapeño; cook, stirring often, until vegetables are softened and onion is translucent, about 6 minutes. Add ground sirloin and salt; cook, stirring often, until beef is no longer pink, about 6 minutes. Stir in taco skillet sauce and beef broth; cook, stirring often, until slightly thickened, 3 to 4 minutes. Stir in tomatoes, beans, corn, and cilantro. Remove beef mixture from heat.

Step 2

Lightly coat a 13- x 9-inch baking dish with cooking spray. Spread 2 cups crushed chips on bottom of prepared baking dish. Top with half of beef mixture (about 3 cups). Sprinkle 1 cup cheese over beef mixture. Spread 2 cups crushed chips over cheese, and sprinkle with 1 cup cheese. Top with remaining beef mixture, and sprinkle with remaining 2 cups crushed chips and 1 cup cheese. Bake in preheated oven until mixture bubbles around the edges and top turns golden brown, about 15 minutes. Sprinkle with additional chopped fresh cilantro. Serve immediately with desired taco toppings.
