place the vinegar in a large bowl and stir in the sugar. Add the chillies and then stir in the cabbage. Cover the bowl and leave to rest in the fridge for at least a day.
blitz the dates and chillies in a food processor. Gradually add some water until a paste is formed. The consistency you are looking for should be thin enough to squeeze out of a tube but thick enough to maintain its shape.
For the avocado mash
combine the avocado with the juice from the lemon and lime. Mash again until almost smooth. Season with salt and pepper and transfer to a small serving bowl. Cover with the olive oil to prevent discolouration.
To prepare the tortillas
cut small circles from the tortillas
you can usually get around two per tortilla. Heat a shallow amount of oil in a deep saucepan until very hot. (CAUTION: hot oil can be dangerous. Do not leave unattended.) Carefully add the tortilla circles to the hot oil and cook for about 45 seconds
or until crisp and golden brown. Transfer using a slotted spoon to a plate lined with kitchen paper.
