Process beans in a blender until smooth then combine remaining burger ingredients in a large bowl. Massage the ingredients together well with wet hands.
Take ½ cup of mixture, roll into a ball and then flatten to form a burger. Chill for 30 minutes.
Heat a non-stick frypan over medium heat, spray with oil and cook burgers, for 4-5 minutes each side.
To assemble, spread sauce on base of roll, add burger, tomato slices and lettuce.
