Make caesar dressing. Place all of the ingredients except the olive oil in a food processor and blend until everything is combined. While the food processor is still running, stream in olive oil until smooth and creamy. Pour 1/2 cup dressing over kale and toss to coat kale. Set aside. You will have leftover caesar dressing.
Form ground beef into four evenly sized patties. Season with salt and pepper on both sides.
In a large skillet over medium heat, add avocado oil. Once hot, place burgers in pan and cook 5-6 minutes each side for medium burgers.
Once burgers are done, plate with a base of kale, the burger on top and parmesan cheese as an optional topping.
