01 - Preheat oven to 400°F. Brush both sides of each tortilla with olive oil. Drape tortillas over upside-down oven-safe bowls on baking sheets to form bowl shapes.
02 - Bake tortillas for 8-10 minutes until golden and crisp. Cool completely before removing from bowl molds.
03 - Heat large skillet over medium-high heat. Add ground beef and cook, breaking apart with spoon, until browned, approximately 5 minutes.
04 - Stir in chopped onion and garlic. Sauté for 2 minutes until fragrant and softened.
05 - Add tomato paste, chili powder, cumin, smoked paprika, salt, and black pepper. Cook for 1 minute to bloom spices.
06 - Pour in beef broth or water. Reduce heat to medium and simmer for 4-5 minutes until mixture thickens slightly.
07 - Whisk together sour cream, lime juice, cilantro, salt, and cumin in small bowl until smooth and combined.
08 - Fill cooled tortilla bowls with shredded lettuce. Layer beef mixture, cherry tomatoes, black beans, corn, avocado, cheddar cheese, olives, green onions, and jalapeño slices.
09 - Drizzle generously with creamy lime dressing. Serve immediately while tortilla bowls remain crisp.
