What type of ribs does the Killer Ribs appetizer feature?

The Killer Ribs appetizer features "fall off the bone" ribs, which are characterized by their tenderness and the way the meat easily separates from the bone when pulled. This cooking style typically involves slow cooking or braising, often resulting in juicy and flavorful ribs that are a signature offering at Texas Roadhouse. The emphasis on the texture and ease of enjoyment makes these ribs a popular choice among diners. The other options, such as spicy BBQ, smoked, or grilled ribs, indicate different preparation methods or flavor profiles that do not specifically highlight the tender, falling-off-the-bone quality unique to this appetizer.
