Walking Tacos

Heat a large skillet over medium-high. Add beef, onion, and garlic; cook, stirring often and breaking up beef using a spoon, until browned, 8 to 10 minutes. Stir in tomato paste, chili powder, cumin, paprika, salt, black pepper, cayenne, and coriander; cook, stirring constantly, until fragrant and tomato paste darkens slightly, about 1 minute. Add 1/2 cup water; bring to a simmer over medium, and cook until sauce thickens, about 25 minutes. Remove from heat, and stir in lime juice. Set aside.

Open chip bags, and top each evenly with ground beef mixture, cheese, corn, olives, pickled jalapeños, red onion, and tomato. Evenly distribute sour cream and ranch dressing among bags. Close bags, and shake well to distribute ingredients.
