So each place has it's own secret sauce, this is the one I use for burgers and dips.
You can use more mayo instead of yogurt for a better spread for burgers.
1/2 cup (120g) Mayo (I use Primal Kitchen)
1/2 cup (120g) Almond Yogurt Kite Hill Plain Unsweetened
16 Dill hamburger Pickle Chips (56g)
2tbsp Dill Pickle Juice
2tbsp Unsweetened Ketchup (I use Primal Kitchen, I even do s spicy version with their spicy ketchup)
1tbsp Sweetener (I use Swerve Erythritol but you can use sugar)
1/4tsp Onion Powder
Place all ingredients in a blender blend until smooth
