In a medium bowl, combine the ground chicken with garlic powder, onion powder, salt and pepper. Mix well.
In a separate bowl, combine the Romaine, parmesan, and caesar dressing. Set aside.
Spread the ground chicken onto the tortillas, dividing it evenly and spreading it almost to the edge of each tortilla.
Heat 1-2 Tablespoons olive oil in a large skillet or griddle over medium-high heat.
Grill the tortillas meat side down for 2-3 minutes or until chicken is golden brown. Flip and grill 1-2 minutes on the other side, watching closely to prevent burning.
Assemble the tacos by adding caesar salad to each tortilla. Sprinkle with toasted panko crumbs.
