In a large bowl add the ground turkey, 1/4 cup of Hellmann’s® mayonnaise, Worcestershire sauce and garlic salt. Mix well and form into four patties.
Heat a large, non stick skillet over medium heat. Add the oil and heat until shimmering. Add the burgers and cook on the first side until browned - about 5 minutes. Flip the burgers and reduce the heat to low. Cover with a lid and cook the burgers until the internal temperature reaches 165 degrees.
Meanwhile, in a smaller bowl mix together the remaining 1/4 cup Hellmann’s® mayonnaise, peanut butter and chopped pickle until smooth.
When burgers are cooked through, serve them on a pretzel bun topped with one bacon slice and a generous dollop of the peanut butter and mayonnaise sauce.
