Put
the lentils in a bowl, cover them with water and
leave to soak for 3-4 hours. Drain well and put them
in a large saucepan.
Add 1 of the carrots, the onion
studded with the clove, bay leaf, thyme and garlic.
Cover with cold water, bring to the boil and simmer
gently for 30-35 minutes. Discard the vegetables,
bay leaf and garlic, and drain the lentils.
Slice
the remaining carrot thinly and blanch with the leek
and celery in a saucepan of lightly salted boiling
water. Drain well.
Meanwhile, make the dressing.
Whisk together all the ingredients in a small bowl
or place them in a screw-top jar and shake well to
combine.
Heat the oil in a frying pan, add the bacon and fry
until crisp.
Stir the blanched vegetables and fried bacon gently
into the lentils, pour over the dressing and toss.
