Dirty Fries

These Dirty Fries are sublime, and the perfect addition to any slimming friendly, Weight Watchers or Low Calorie meal which the whole family will love!

Last year we came up with a Dirty Rice, and it’s fair to say that it was one of our most popular recipes EVER. These Dirty Fries will be another favourite as they’re sooooooooo good!! Dirty Fries | Slimming & Weight Watchers Friendly

For the full list of ingredients and comprehensive instructions, please see the recipe card at the end of this post. Before you scroll, there’s important stuff in the blurb 👍

Bacon, potatoes and Cajun spice may sound like a bit of an odd mix, but it’s truly amazing. It has to be one of our favourite combinations ever.

Dirty Rice and Dirty Fries get their names from the appearance of the finished dish. They’re usually finished with chicken livers, which give them a brown appearance. (We’ve obviously left them out mind!)

If you’re looking for some other potato accompaniments, we’ve got a load of tasty recipes!
