Whisk together all ingredients for burger spread. Cover and refrigerate until ready to use.
Heat a grill to medium heat. Season burger patties liberally with seasoning salt. Cook until desired doneness. Transfer to a plate and cover to keep warm.
Meanwhile while burgers are cooking fry the pickles. Whisk together egg, milk, hot sauce, Worcestershire and 1/4 cup flour. On another plate combine panko, remaining flour, granulated garlic, pepper and salt.
Dip each pickle into the wet ingredients and then dredge in the bread crumb mixture.
Heat oil in a skillet over medium-high heat. Cook pickles, in batches if necessary, until golden and brown. 1 - 2 minutes per side. Transfer to a paper towel lined plate and sprinkle lightly with salt.
Assemble the burgers: Place lettuce on the bottom bun and place cooked burger patty on top. Spread burger spread on top of burger and top with 4 - 5 fried pickles. Repeat until 4 burgers are made. Serve immediately.
