Falafel with tahini sauce

Tonight I made falafel with tahini sauce. It was surprisingly easy. It was pan fried but I might actually try baking it next time. 

For the falafel:
1 chopped white onion
3 garlic cloves
1 can chickpeas, drained
1/2 cup parsley leaves
1/2 cup cilantro leaves
1 teaspoon salt
¼ teaspoon chili powder
1 1/2 teaspoons cumin powder 
1 teaspoons baking powder
½ cup all-purpose flour

Vegetable oil, for pan frying
Pita or naan bread, for serving

Lemon slices to squeeze over 

For the tahini sauce:

1 single serve cups plain Greek yogurt
¼ cup tahini 
Juice and zest of 1 lemon

Salt and pepper 

Pulse onion and garlic in food processor until minced, set aside. Pulse spices, herbs, beans until just chopped. Add back onions and baking soda and pulse till combined. Slowly add flour 1/4 cup at a time till firm enough to mold into patties. Put in fridge while you mix sauce together, preferably leave it In fridge for like an hour. Pan fry in hot oil for 3 minutes per side. Salt as soon as done, squeeze lemon over top and serve with sauce on naan bread.
