LET’S GET IT TOGETHER !
Step 1: Add oil to cast iron pan over medium-high heat until oil is just smoking. Divide meat into four loose balls. When pan is hot, drop meat carefully onto pan and smash down with a stiff metal spatula. Add salt and pepper generously, then let sit, undisturbed, 2-3 minutes, until edges are crispy. Flip burger, add more salt and pepper, and cook another 2-3 minutes until burger is cooked to desired doneness. Add cheese, if desired, about 1 minute before burger is done cooking.
Step 2: Place burger on soft bun, top with toppings as desired and serve with warm waffle fries.
