Preheat your oven to 400°F (200°C).
In a large skillet over medium heat, add the lean ground beef. Use a spatula to break it up as it cooks. Sprinkle in the garlic powder, onion powder, smoked paprika, ground cumin, chili powder, and tomato paste. Stir well and cook until the beef is browned, about 7-10 minutes.
Line your sheet pan with Reynolds Wrap Non-Stick Foil and spread the tortilla chips across the pan in an even layer.
Evenly distribute the cooked beef mixture over the tortilla chips. Then sprinkle the corn, black beans, sliced black olives, and jalapeno peppers on top. Finally, generously cover everything with shredded cheese.
Place the sheet pan in the preheated oven and bake for about 10-15 minutes, or until the cheese is melted and bubbly.
Once out of the oven, add chopped tomatoes, avocado, cilantro, and red onion over the nachos. Drizzle with sour cream and serve immediately.
