Spinach and white bean veggie burgers prove that a meatless burger can still be big and sloppy and loaded with lots of fixings. These hearty beanburgers come together with white beans, spinach, garlic, onions, feta, and panko and are smothered in a bright and fresh yogurt cucumber sauce. Top ‘em off with sweet potato shoestrings for extra crunch -- and more veggies!
Drain and rinse one can of white beans. Place in a medium bowl and smash with a fork or potato masher.
Squeeze all the water from the spinach. Just when you think you’ve gotten it all, wrap it in a paper towel and squeeze again. Add the spinach to the beans.
To the bean and spinach mixture, add the chopped onion, sliced green onions, garlic, dill, parsley, oregano, red pepper flakes, lemon juice, ⅓ cup feta, ½ cup panko, and one egg.
Mix everything together, getting in there with your hands (like meatloaf), if necessary.
Shape mixture into patties. I made 4 hefty-sized patties because I had giganto hamburger buns. You can easily get six good-sized patties for normal sized buns.
Place remaining panko in a bowl and roll the patties in it.
Heat 1 tablespoon oil in cast iron skillet. Cook patties for about 4 minutes per side, or until golden brown. Serve with feta, tzatziki sauce, sliced tomato, cucumber, and toasted buns.
Tzatziki Sauce
In a medium bowl, mix the yogurt, lemon juice and zest, dill, garlic, shredded cucumber, olive oil, salt and pepper. Voila.
