Radicchio, banana and avocado salad with dates and a ginger- lime dressing

This is very unusual but sensational. Bananas and avocado have a very similar texture and the Asian dressing lends itself really well to this combination. I would love to hear what you think of it.

Serves 6 as a starter.

2 medium heads of radicchio
6 Medjool dates, pitted
2 firm bananas
2 ripe avocados

For the dressing
3 tbsp safflower oil
2 tbsp lime juice, freshly squeezed
2 tbsp Thai fish sauce
2 tbsp light brown sugar
2 tsp Asian chile sauce
1 tbsp finely minced ginger
1 tbsp chopped mint leaves
1 tbsp chopped cilantro sprigs

Pull apart the radicchio leaves, then tear away and discard the bitter white stem area; you should have abut 4 cups. Keep in the fridge until you’re ready to make the dish.
Thinly slice the dates. In a small bowl combine all the dressing ingredients and refrigerate until needed.
When ready to serve, slice the bananas and cut the avocado flesh into 1/4 slices. Stir the dressing, place the radicchio in a bowl and toss with just enough of the dressing to barely coat the leaves.
Transfer the leaves to salad plates and put the dates, banana and avocado slices in the same bowl, add the rest of the dressing and very gently toss together.
Place this mixture on top of the radicchio and serve at once.
