Make filling: In large bowl, combine ground beef, Tony's, garlic powder, onion powder, smoked paprika, cumin, black pepper, tomato paste, parsley, diced onion, jalapeño if using, olive oil, and lemon juice. Add cheese if using. Mix until just combined. Don't overwork.
Prepare pitas: Cut 6 pitas in half to create 12 pockets. Gently open each pocket. Divide meat filling into 12 equal portions (about 1.5 to 2 ounces each).
Stuff pitas: Spread one portion of filling inside each pita pocket in thin, even layer about ¼ inch thick, reaching to edges. Press stuffed pita flat to ensure even thickness.
Brush and preheat: Brush both sides of each stuffed pita with olive oil or melted butter. Preheat grill, griddle, or skillet to medium heat (350°F to 375°F).
Cook: Place arayes on hot surface without crowding. Cook 3 to 4 minutes per side until golden brown and crispy with meat cooked to 160°F internal temperature. For pellet smoker: cook at 350°F for 10 to 12 minutes, then increase to 425°F and crisp 2 to 3 minutes per side.
Make garlic butter: Melt butter and stir in Tony's, garlic powder, and parsley. Keep warm.
Finish: Brush hot arayes with garlic butter immediately after cooking. Serve hot with dipping sauce if using.
