Assemble: ingredients. Wash and part dry all the greens.
Cut and add the veggies to a food processor. Or you can grate broccoli, zucchini, onion, and garlic on the medium coarse side of a box grater and finely chop the spinach.
Pulse until it looks like quinoa. This should not take long, a couple of ‘pulse,’ and you are done. If you let it run for too long, you will end up with a mushy paste of veggies and that will be too difficult to bind.
Transfer the veggies to a muslin cloth and squeeze out the excess water. This step is important. If the water is not squeezed, the mixture will become runny and difficult to handle.
Add chili sauce, mustard paste, cumin seeds, salt, crushed black pepper, and paprika.
Finally, add gluten-free flour - chickpea flour. You can use any gluten-free flour. See notes above.
Knead the mixture like a dough. The dough should not be sticky. If it feels sticky add an extra teaspoon of chickpea flour and knead again.
Divide the mixture into 6 big round balls. Shape and flatten each ball into patties.
Pan cook these patties until evenly brown. I have cooked these green veggie patties in an air-fryer @370 degree F for 10 minutes.
Time to assemble the burgers. Slightly toast burger buns in a toaster. Layer the bottom bun with cilantro mayo dressing.
Top with lettuce, tomato, and onions. Other topping options include - pickled onions, pickled cucumbers, or regular cucumbers.
Add the green veggie patty.
Drizzle some more cilantro mayo dressing, top it with another slice of onion/tomato if you like and finally add the top bun layer.
Delicious burgers are ready to be devoured.
