Sage and Onion Lentils

What can i say - no flash on the iPhone and only 2 megapix, so not a great picture - come back nokia, all is forgiven.  Here's the sage and onion lentils we had with the cod, although i think i'm going to recommend more sage than nigella suggests as i couldn't really taste it.  12 sage leaves in 500g lentils and 3 onions get lost a bit i reckon.

- Put 500g puy lentils in a pan, and add 3 whole cloves garlic, 2 whole peeled onions, 10 sage leaves, and 1 stick celery halved.
- Cover with cold water, bring to the boil, add 1-2 teaspoons salt and simmer for 35 mins.
- Drain and remove the lentils and add 6 tablespoons olive oil.
- When hot, add 1 finely chopped onion and 10 more shredded sage leaves.
- Cook for 10 mins, then add 2 cloves chopped garlic and teaspoon mustard.
- Cook a further couple of mins, then add back the lentils and stir well.
- Season and add olive oil and lemon juice to taste.

You can just see them poking out from under the cod...
