Preheat the grill to medium high. In a small skillet heat the olive oil over medium heat. Add the scallions and sauté for about 4 minutes, until the scallions are softened.
Turn the scallion mixture into a large bowl and add the barbecue sauce, bread crumbs, and pureed chipotles and stir to combine. Add the turkey and salt and pepper and mix well, using your hands or a spoon, but trying to handle the meat lightly. Form the mixture into 4 evenly-sized patties, and once the patties are well shaped use your fingers to press an indent into the middle of each patty – this will help them remain flat when they cook, as they will naturally swell in the center.
Grill the burgers for about 5 minutes on each side until they are cooked through and have reached an internal temperature of 165 F on an instant-read thermometer. While the burgers are cooking, in a small bowl combine the mayonnaise and the chipotles in adobo.
Place the cooked burger on the bottoms of the buns, top with the sauce, and layer in any toppings you like. Serve immediately.
Notes
Internal Temperature for Turkey Burgers:
Finally, take the burgers off of the heat the second they are cooked through, as they will continue to cook a bit after being removed from the direct heat. You want to cook turkey burgers to an internal temperature of 165 F – that’s when they are just safely cooked through (get that meat thermometer!). Turkey burgers should not be served rare.
