Pulled beef burgers are tender and savory. Some sort of light vegetable paired with a crunchy topping makes for great additions to pulled beef burgers. We use quick pickle onions and radishes in this recipe, but a cole slaw, red cabbage, and spinach are also great vegetables to put on this burger. We also top with crispy jalapenos, but crispy or sauteed onions, cheddar cheese, and potatoes are also amazing toppings!
