Add the chickpeas, garlic, red onion spinach, cilantro and parsley to a blender or food processor and pulse together until a textured paste forms- you may need to scrape down the sides every now and then. The mixture should still have small pieces of herbs and chickpeas and doesn't need to be fully pureed. *See pictures above
Transfer the mixture to a large bowl and add in the spices, sesame seeds and flour. Mix together using your hands, making sure everything is evenly mixed. If the mixture is too pureed, I suggest adding an extra 2-3 tbsp of flour.
Form 4 palm-sized burgers with the mixture.
BAKE OR PAN-FRY: Pan-fry: heat a skillet with about 2 tbsp olive oil on medium heat. Cook the burgers for about 5-7 minutes on one side, and flip them for another 5 minutes. Bake: preheat the oven to 375 F. Place the burgers on a parchment lined sheet pan and drizzle them with olive oil. Bake them for 12 minutes, then flip and bake for an additional 10 minutes.
To make the tahini sauce, combine the tahini, water, lemon juice, salt and garlic in a bowl and whisk together until smooth. Start with 1/4 cup of water and add more as needed to create a smooth sauce.
Toss the cucumbers, tomatoes and herbs together with the olive oil, lemon juice salt and pepper and serve with your falafel burgers and tahini sauce.
The burgers can be frozen for up to 3 months.
