This recipe has become a regular in our house. As other comments suggest, it's better without the soy sauce in my opinion. I have made this with the addition of chillies and replaced the thyme with fresh coriander. It has cooked beautifully every time!

added a chopped green jalepeno to the base sauce - adds extra depth of flavour and a slight heat kick

followed other tips and left out the soy sauce. Added some garlic paste and chilli flakes. Simple and tasty

This is a great base recipe . As per other comments I gave up on the soy sauce and I added some garlic, chillies, chorizo, tomato paste, a splah of white wine and increased the amount of thyme. Served with baked baby potatoes , it came out delicious .

This was quick and easy - followed the recipe - but there was a thick watery tomato liquid on the plate (Waitrose own brand chopped) and I should have added tomato puree to give it colour and taste.

Really easy and really quick to make. I added capers, garlic, chilli, and more thyme. Left out the soy. I had it with lemony couscous. Delicious.

Really disappointing and lacking in flavour. I did as others suggested, left out the soy and added garlic and plenty of thyme, but was really bland.I also made the crispy garlic and roast potatoes as someone suggested, next time i will cook potatoes for a bit longer then grill at a higher heat as not crispy enough

Delicious mid week supper. I added a clove of garlic, half a chilli and asparagus which I pan fried once the onions had browned which gave it a bit of zing!

I followed advice and left out the soy, added garlic and olives and extra half tin of toms. Everyone enjoyed it including my 4 year old. I am a veggie so used quorn pieces...will try with tofu next time. Quick and tasty!

I used 1 tsp of soya sauce instead of 1 tablespoon, added more thyme and a tsp of mixed herbs, plus 2 cloves of garlic. Absolutely delicious.
