What size tomato tin ?

    Hey Terry, it’s a 400g tin of chopped tomatoes in this recipe, hope that helps!

Hi! I love this soup but was wondering about adding rice to it to make it even more filling. Would that work do you think? I don’t eat much bread…

    SharonTuesday 1st November 2022

    Hi Amanda, adding rice to the Chunky Tomato Cajun Soup should work well. We haven’t tested this ourselves, but would suggest adding a little rice in step 5 with the kidney beans, chickpeas and sausage and then cook for around 45 minutes to an hour, or until cooked. Hope you enjoy the recipe!

If using a slow cooker is it 3 hours on high?

CerysSunday 29th January 2017

My slow cooker is a very small one so could I just use a big stew pot and simmer gently for 3 hours?

Reply

    KateSunday 29th January 2017

    Hi Cerys
    Yes you could cook it in a pan on the stove for a few hours without any problems.

Can you cook this with the pressure cooker setting of an instant pot? If yes, how long for?
Thanks

    Hi Kate,

    Yes you can. When you get to step 4 you can cook for 15 – 20 minutes on manually with natural pressure release
