Can you add double the amount of chilli powder rather than 1tsp of chilli flakes? Or is there an alternative to chilli flakes?


    HollyTuesday 18th May 2021

    Hey Tracey, yes if you like things a little hotter feel free to double the amount of chilli powder, or just omit the chilli flakes if you don’t have them hope that helps!

what can i add to make it creamy


    HollyWednesday 20th January 2021

KatieTuesday 6th October 2020

Hi – how many grams of chicken should I be using to serve 2? Trying to calorie count and have bought mini chicken Breast fillets and so I need to work out how many grams would be in 1.5 fillets.



    HollyWednesday 7th October 2020

    Hey Katie, an average chicken breast weighs approximately 150g so for this recipe you would need approximately 450g of chicken. Hope that helps!

I love the taste of this mixture, I made it and also added some chopped garlic and tomatoes just for a bit more veg as I’m watching the weight, and it’s so tasty!


    LisaMonday 18th May 2020

    Thanks for your comment, Matthew. You can never have enough veg in my opinion! So glad you enjoyed it.


Bianca Di CantoMonday 27th April 2020

Hi, is the 240 cals just for one portion or for the 4? Also I’m guessing it doesn’t include the wrap? X

Could you substitute the tortilla wraps with Lo-dough?


    Holly LevellThursday 14th May 2020

    Hi Viv, I’m sure these Chicken Fajitas would work well with the Lo-Dough tortilla wrap equivalents


Julie SandersonTuesday 11th June 2019

How many total carbs are in this recipe want to make it but trying to cut down on carbs


    Emma TThursday 20th June 2019

    Hi Julie,

    We’d recommend using a nutritional calculator to find out this info ????


Jade RossTuesday 12th March 2019

The calories per person is that including a wrap? Just we are a picky household I do veg and the other half has the chicken so trying to calorie count! X


JaneTuesday 5th March 2019

How easy would this be to do in the oven? No hob facilities where I’m staying for a few weeks!


John NewallWednesday 9th January 2019

I love this recipe. Its similar to one i used for ages. I slow cooker mines just purely for ease and tbh best results. I also tried adding some garlic and herb passata to it, to give it a nice sauce and to prevent it from being too dry.
