Add potatoes to a pot, cover with water, and boil for 10-15 minutes until fork-tender. Drain and mash the potatoes with a fork. Season with salt and pepper.

In a large bowl, mix the mash potatoes and brussels sprouts. Season generously with salt and pepper.

Form into patties (use number of patties listed in recipe details).

Heat oil in a skillet over medium heat. Press patties into the oil and leave undisturbed until browned on one slide, about 2-3 minutes. Flip and cook the other side.

Serve with a dollop of Greek yogurt.
