Garbanzo Beans Croquettes

0 In the bowl of a food processor mix the garbanzo beans, onions, egg, gruyere cheese, oregano, garlic and 1 tablespoon olive oil. Mix until you reach a thick paste. Transfer to a bowl and add the breadcrumbs. Season with salt and pepper and let it rest for 10 minutes.
1 Meanwhile prepare the tahini sauce by adding all the ingredients in a bowl and season to desired taste. 
2 Slightly wet your hands and grab one spoonful of the garbanzo mix. Roll it and then slightly flatten. You can also use an ice cream scooper, roll and flatten.
3 In a large skillet heat, add the remaining 2 tablespoons olive oil and fry the croquettes 2 minutes approximately on each side. Transfer to a paper towel to drain any oil excess. 
4 Serve the croquettes with the sauce.
