For the Dressing:

Combine all ingredients in a mixing bowl and whisk until well incorporated. Best if made a few hours or days in advance.

For the Burgers:

1. Combine all the ingredients in a bowl and mix to combine. Using dampened hands, form the mixture into 4 patties.
2. Heat a large sauté pan over medium-high heat. Add the olive oil and heat until shimmering. Add the burger patties to the pan and cook for 5 minutes per side, until golden and cooked through.
3. Add the buttered buns to the pan and turn the heat down to low. Cook for 1 minute, just to warm through and crisp the bread just slightly. While warm, rub the inside of the bun halves with a halved garlic clove. Set aside.

For the Frico:

1. Preheat oven to 400°F and line a rimmed baking sheet with a silicone baking mat (alternatively, you could use parchment paper).
2. Mix together the two cheeses and then transfer to the baking sheet in heaping tablespoons. Gently flatten the cheese mounds just slightly.
3. Bake for 3-5 minutes or until golden and crisp. Cool completely on the baking sheet.

To Assemble:

Spread a little bit of the dressing on the bottom burger bun, then top with a burger patty, sliced pickles, and a handful of the shredded lettuce. Drizzle everything with a little bit of dressing and then top with the cheese frico and the top bun. Enjoy!
