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, with no pink showing. Cook the pepper and onion slices on the barbecue, until softened.
Serve in toasted buns with lettuce, the peppers and onions, and some guacamole.
