Preheat your oven to 425 degrees Fahrenheit. Line a baking sheet with parchment paper.
In a small food processor, pulse the chickpeas and parsley until coarsely chopped.
Transfer to a mixing bowl and add the quinoa, almond flour, cumin, coriander, cayenne, and sea salt; stir until well combined.
Lightly grease the parchment paper with oil. Portion the mixture into 8 mounds on the baking sheet.
Bake for 30 minutes, then flip and bake for another 10 minutes until firm.
For the tzatziki, blend the cucumber, parsley, lemon juice, yogurt, and salt until smooth.
Assemble the burgers by spreading tzatziki on the buns, adding the patties and more tzatziki.
Serve and enjoy immediately, or store each element separately for later.
