Step 1

Make Burger Patties: Combine and mix together all burger patty ingredients in a large bowl. Form into 4 patties, and refrigerate for at least 1 hour to harden.

Step 2

Toast Buns: Heat a pan over medium heat, or use a grill. Working in batches, drizzle inside faces of buns with cooking oil and place face down on the pan. Cook until toasted, a few minutes. Transfer to a serving plate.

Step 3

Cook Burger Patties: Increase to medium-high heat (or keep at medium heat to lessen the amount of smoke; it will just take longer to cook). Drizzle cooking oil over pan. Working in batches, cook patties until charred on both sides and internal temperature reaches 160°F, flipping occasionally. Add more oil if the pan gets dry.

Step 4

Serve: Assemble burgers by distributing patties and toppings among buns. Serve hot.
