Mix together the guacamole ingredients. Season and set aside for the moment.
For the burgers, heat the oil in a pan and sauté the onion and the remaining 2 garlic cloves for a few minutes. Allow them to cool, then tip into a bowl and add the parsley, mince and chilli powder. Season and mould into 4 burgers.
Brush the burgers with oil and grill for about 4 minutes each side until cooked through. Cook the pepper and onion slices on the barbecue, until softened.
Serve in toasted buns with lettuce, the peppers and onions, and some guacamole.
