Walking Tacos

1 pound 85% lean ground beef

1 cup chopped yellow onion

3 garlic cloves, minced 

1/4 cup tomato paste

1 teaspoon chili powder

1 teaspoon ground cumin

1 teaspoon smoked paprika

1 teaspoon kosher salt

1/2 teaspoon black pepper

1/4 teaspoon cayenne pepper

1/4 teaspoon ground coriander

1/2 cup water

2 tablespoons fresh lime juice

4 (1 3/4-ounce) bags nacho cheese–flavored chips (such as Doritos) 

4 ounces sharp cheddar cheese, shredded (about 1 cup)

1/2 cup corn kernels

1/2 cup sliced black olives

1/4 cup pickled jalapeños

1/4 cup chopped red onion

1/4 cup chopped tomato

1/2 cup sour cream

1/4 cup ranch dressing

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.
