Cut tops off peppers; remove and discard stems; scoop out seeds. Set aside.
In a medium skillet over medium-heat, heat olive oil. Add ground beef, POM Wonderful 100% Pomegranate Juice, cumin, salt, and pepper, breaking meat apart with wooden spoon. Cook until meat is browned and cooked through, about 5 minutes. Add cooked rice to beef mixture; mix well.
Preheat oven to 375°F. Stuff each pepper with rice-beef mixture. Bake for about 15–20 minutes (covering halfway through with tinfoil). Peppers should be soft and tender.
Top peppers with feta cheese, POM Wonderful Pomegranate Arils, and chopped parsley.
