Cook the vegetables
separately in a saucepan of salted boiling water for
4 to 5 minutes. Drain well and chill.
To make the
dressing, heat the oil in a frying pan and fry the
peanuts, tossing frequently, for 3 to 4 minutes.
Remove from the pan with a slotted spoon and drain
on kitchen paper. Process the peanuts in a blender
or food processor or crush with a rolling pin until
a fine mixture is formed.
Pour all but 1
tablespoon of the oil from the pan and fry the
garlic and onion for 1 minute. Add the chili
powder, sugar, a pinch of salt and the water and
bring to the boil.
Stir in the peanuts. Reduce the
heat and simmer for 4 to 5 minutes, until the sauce
thickens. Add the lemon juice and set aside to cool.
Arrange the vegetables in a serving dish and place
the peanut dressing in a small bowl in the centre.
