To make these tacos, start with the falafel. Add the roughly chopped onion, garlic cloves, and drained garbanzo beans to a large food processor and process until they break down into fine crumbs.
Then, add the parsley, cilantro, cumin, chili powder, coriander, cinnamon, baking powder, and kosher salt, and process again until the mixture becomes a thick paste. You’ll likely need to stop and scrape down the sides a few times. Be patient, it will come together!
Next, make the lemon tahini sauce. In a bowl, whisk together the lemon juice, olive oil, tahini, honey, red wine vinegar, garlic powder, sea salt, and black pepper. If it’s too thick, add water a little at a time until it’s drizzly. Taste, adjust the seasonings as needed, and set it aside.
Now, assemble the tacos. Add a large spoonful of the falafel mixture to each pita and spread it out evenly.
Heat a large skillet over medium heat and add 1 teaspoon of avocado oil. Once the pan is hot, place a pita in the pan falafel side down and cook for about 3 minutes, until the falafel is golden and crispy.
Flip it over and cook for another minute or so to crisp up the bread. Transfer it to a plate and repeat with the remaining tacos, adding another teaspoon of oil to the pan for each one.
Finally, add your toppings: the lemon tahini sauce, pickled onions, baby tomatoes, parsley, and sesame seeds. Fold them up like a taco and enjoy! Store any leftover falafel mixture, sauce, and toppings separately in airtight containers in the fridge.
