Can I use a grill instead of the broiler?
Yes. Form the beef mixture into patties or logs, place on an oiled grill grate over medium-high heat, and cook 4–5 minutes per side until golden and cooked through.
What's the best way to keep the pitas warm?
Wrap them in a clean kitchen towel immediately after warming, or place them in a covered container. This traps steam and keeps them soft and pliable.
How do I know when the beef is done broiling?
The surface should be golden-brown and slightly charred in spots. Internal temperature should reach 160°F. Check doneness at the thickest point with a meat thermometer.
Can I make the beef mixture ahead?
Yes. Form the seasoned beef into patties or a log, cover, and refrigerate up to 24 hours before broiling.
What if I don't have Greek yogurt for the aioli?
Use sour cream or mayonnaise as a 1:1 substitute, though the tanginess and texture will differ slightly.
