Process Greens: In a high-speed food processor, add spinach (or Swiss chard), celery, rosemary, and parsley. Blend on high until all greens are completely chopped. Set aside. Pour greens into a large mixing bowl. Set aside.
Prepare Veggie Mix: To the processor, add the drained chickpeas, avocado, tomato, onion, garlic, turmeric, cumin, paprika, salt and pepper. Blend on high until smooth but still a little chunky. The chickpeas should just be turning smooth.
Combine Mixtures: Pour the chickpea mixture into the bowl with the greens. Mix until well combined.
Add Flour: Sprinkle in the flour and mix until well combined.
Form Patties: Shape the mixture into burger patties, sized to fit your buns. Set them aside on a tray or plate.
Cook Patties: Heat a tablespoon of coconut oil in a large skillet over medium-high heat. Place the formed patties into skillet, cooking in batches if needed, and cook for 2-3 minutes on each side or until dark golden and fully cooked. Repeat with the remaining mixture, adding an extra 1 tablespoon oil when needed to coat the skillet.
Assemble Burgers: Slice the burger buns, add the cooked patty and place in your desired fillings and close the bun.
Serve and Enjoy: Serve the vegetarian burgers hot with a side of fries or a fresh salad. Enjoy!
