Much like its close cousin, the sandwich, a burger is wonderfully adaptable, catering to individual preferences without much fuss or extra effort. To adapt this burger recipe, you can make changes to the patty or include other toppings or condiments. For the patty, any other variety of beans or chickpeas can substitute the white beans, offering different flavors and nutritional benefits. If you're after a smoky and spicy kick, you can increase the paprika and the hot chili powder in the patties.
