Coleslaw with vinaigrette

I really like this salad. It is quite tart when fresh, but mellows wonderfully of the next few days if you don't eat it all in one go. The juices from the carrots and the cabbage leach out and blend with the vinaigrette as the flavours meld over time.

1lbs/455g cabbage (recommended is ½ green cabbage and ½ red cabbage), finely sliced

2 large carrots (6oz/170g) grated

2 scallions, finely sliced (30 to 40g)

¼ cup (60g) Tbsps apple cider or white wine vinegar

1 Tbsp + 1 tsp (25g) Dijon mustard

1 tsp salt 

1 tsp pepper

½ cup (100g) good olive oil

1. Prepare all the vegetables and mix in a large bowl.
2. Put the remaining ingredients in a small jar, screw on the lid tightly and shake until emulsified, just a few seconds.
3. Pour the dressing over the vegetables and mix together thoroughly.
