In a mixing bowl, combine ground lamb or beef, Worcestershire sauce, grill seasoning, and ground cumin.
Gently mix until just combined, being careful not to overwork the meat.
Form the meat mixture into 6 small, evenly sized patties to match the rolls.
Heat a skillet over medium-high heat and drizzle with olive oil.
Cook the patties for about 4-5 minutes on each side, or until nicely browned and cooked through.
While the patties cook, lightly toast the split dinner rolls in a separate pan or oven.
Drizzle a bit of extra-virgin olive oil on the toasted rolls for added flavor.
Assemble the sliders by placing each patty inside a roll.
Serve warm, optionally adding your favorite toppings like sautéed onions, cheese, or fresh greens.
