    A side dish of keto roasted cauliflower roasted in Djjon mustard and lemon butter sauce is an easy and tasty recipe.

    If you are a fan of mustard, then this dish is simply divine and the addition of the lemon is lovely.  I had to stop myself eating the whole dish once I tested a piece after it was cooked. This is a wonderful side dish that could steal the show from the main course!

      I had some leftover pasta and I wanted a sauce with lemon since that was pretty much the only thing I had in the house. Seven minutes after finding this recipe I was eating. So simple... The Dijon mustard combined with lemon and butter is delicious. I am making the full recipe tonight with roasted cauliflower.

      I love whole grain dijon mustard - I've been addicted to it lately. Thank you so much for sharing this recipe! I have been trying to find more dishes that use dijon mustard and this one is definitely on the list.

        I agree with you about Dijon! It really makes this dish with the lemon and I hope you find it as addictive as I do!
