Step 1. Fill a heavy-based frypan or pot with oil. Heat the oil over medium-high heat until the temperature reaches 180C. You can test the heat of the oil by dropping a small amount of falafel mixture in. If the mixture sizzle immediately the oil is ready. 
Step 2. Fry the falafel patties in batches, for 4-6 minutes or until a nice deep golden brown develops and they are cooked through. Using a slotted spoon, remove the falafels from the oil and transfer them to a tray lined with a paper towel to drain. Sprinkle with salt. Repeat with the remaining falafel mixture. 
Step 3. Place all ingredients for the sriracha sauce into a small bowl, mixing thoroughly to combine. Taste and adjust to suit your palate. 
Step 4. Place a frying pan over high heat. Working in batches toast the buns on the frying pan for 15s or until slightly charred. Once toasted "butter" the buns with Nuttelex Olive Spread.
Step 5. To assemble, place a small amount of sriracha yoghurt on the base of the bun. Top with the lettuce, falafel burger patty, sumac onions, and additional sriracha yoghurt. 
 
For an alternative to chips we like to serve our burgers with a side of blanched salted green beans.
