1. Crack an egg into a large bowl and beat well. Using a potato masher or the back of a big wooden spoon, add the beans and mash them together with the egg until relatively smooth but with some chunks remaining. Fold in the cooked quinoa, then add the rest of the ingredients. Mix until combined.
2. Roll small handfuls of the batter into balls the size of clementines. Press down to form a patty that should be about 3 inches in diameter. If you're having trouble getting your burgers to adhere, add a bit more egg and mix to combine.
3. Heat a bit of oil in a pan over medium. Cook the patties in batches about 3-4 minutes a side, until golden brown.
4. Assemble your burgers. Add any desired toppings and spreads. Serve.
