Prepare grill (or broiler).
Place scallions in a food processor; pulse until chopped, about 10 pulses.

Add turkey, egg, mustard, Worcestershire sauce, pepper, and 2/3 of the salt; pulse until combined; about 30 seconds.
Divide mixture into equal parts.
Shape into burgers.
Combine red onions with sugar, vinegar, and remaining salt in a medium-sized mixing bowl.
Toss thoroughly to combine.
Set aside to marinate for a minimum of 15 minutes.

Serve burgers with washed lettuce, marinated red onions, and mayonnaise on a toasted bakery roll.
If desired, stir some pesto into your favorite mayonnaise to create a pesto mayonnaise spread.
