Notes

  • The nutrition information above does not include the burger sauce or toppings. 
  • You can prep the burger patties 1-2 days in advance and the burger sauce up to 3 days ahead of time. Store them in separate airtight containers in the fridge. Then, reheat them in the microwave or a cast iron skillet over medium-high heat, and assemble your burgers when you’re ready to eat.
