In a large mixing bowl, combine the ground beef, harissa sauce, olive oil, cumin, salt, and pepper. Mix well until evenly combined.
Heat a skillet over medium heat. Add the seasoned beef mixture and cook for about 8-10 minutes, stirring occasionally, until fully cooked and browned.
While the beef is cooking, warm the pita breads in a dry skillet or microwave for about 1-2 minutes until soft and pliable.
Once the beef is cooked, remove from heat and let it rest for 5 minutes to allow the flavors to meld.
To assemble, cut the warm pita breads in half, creating pockets. Stuff each pocket with a generous amount of the beef mixture, followed by diced beets and a handful of fresh arugula.
Optional: Sprinkle sesame seeds on top before serving.
Serve cut in half with a simple side salad of your choice—enjoy your tasty creation!
