Griddled sweet potato with ginger, chilli and lime

You might have noticed that ginger, chilli and limes feature frequently in my recipies.  I love the combination of them!
4 medium sized sweet potatoes
200 ml extra virgin olive oil

For the dressing:
5 tbsp lime juice
3 tbsp chopped fresh coriander
2 tbsp runny honey
4 tsp grated fresh ginger
1 red chilli, deseeded and finely chopped
2 garlic cloves-crushed
salt and black pepper

Peel the sweet potatoes, and cut into thin slices, about 3 mm thick.  Blanch the slices in boiling water for a couple of minutes.  Drain them and allow to dry.  Put the slices in a bowl and smother with the olive oil.
Heat the griddle pan and cook the potato slices for 3-4 minutes on each side-it is quicker to put the whole lot in a baking tray under the grill-but you dont get the pretty stripes!
Make the dressing by mixing all the ingredients together and drizzle over the sweet potatoes while still warm.  This is yummy hot or cold!
