Use tinned puy lentils instead of dried, and skip boiling them first!

This was the first time I had cooked marrow and I decided to use this recipe but I used haloumi cheese instead of feta - and it was delicious! Such a great mix of textures and flavours. The only issue I had was that I got a bit over excited and put a few too many chilli flakes in which made it a bit too spicy, so if cooking it yourself stick to what is stated in the recipe! - 12 Sep 2010
Used different ingredients. I've added 3 spring onions and used fresh chillies. I slightly cooked these with the garlic in olive oil before adding the lentils. - 27 Mar 2011
Something else. I added leaks (because I love them!) and a little bit more feta cheese; the extra cheese balances the mint out a bit better. - 30 May 2010
