Mix beef, almond meal, egg, ketchup, pine nuts, and a little salt in a large bowl.
Using your hands form into patties. It’s up to you how big or small. I like mine medium sized so they don’t take too long to cook.
Heat a little oil in a frying pan on a medium high heat and cook rissoles for about 5 minutes on each side until well browned and just cooked through. Be careful as the sugar in the ketchup makes them easy to burn.
Serve with salad leaves or however you like your burgers.
