In this tutorial, Caroline Artiss shows us how to make coleslaw for barbecues. You will need: half a cabbage, 3 medium carrots, 1 red onion and mayonnaise. To start, slice all of this up as finely as possible with a very sharp knife. You can also use a blender to do this if you don't want to do it by hand. Now, take your veggies and cabbage and place it into a bowl. Once you've done this, place 3 tbsp of mayonnaise, 1 spoonful of soft brown sugar and 1 spoonful of white vinegar and mix together. You can add salt and pepper to taste as you like. Once mixed, pour it over your veggies and mix together well!
