    question for anyone who's tried this already: my sweetheart doesn't like cauliflower - has anyone tried substituting any other vegetable? How did it go? Thanks so much!!!

    Zucchini,yellow squash, chayote.
    Other milder tasting vegetable from the cabbage family like chinese cabbage or bok choy, turnip or kohlrabi.

    I made this last night. The Dijon mustard overpowered the dish. It's not edible. :o(

    there are about three pounds of ingredients in this recipe. a mere tablespoon of dijon overpowered it and rendered it inedible for you? perhaps you added an incorrect amount. i thought the casserole was delicious--even my young nephews enjoyed it.
  5. Mary
    I am not big on sauces and I do not like dijon so I used regular mustard, and only about 1/4-ish tsp of it.
    Gave a good tang to the mixture - like a burger would taste (to me).

    This is fantastic with grated zucchini (instead of cauli) and regular mustard :-D

    Love this recipe... just have 1 question, why whole tomatoes only to chop it up anyways? Why not just put chopped tomatoes on the ingredients list instead?

    My 7 year old devoured this! We chopped the cauli and he ate it no issues at all.

    Just curious why this dish is not Keto? Could it be used in a keto diet if you still fall under 20 carbs a day?

    Just curious why this dish is not Keto? Could it be used in a keto diet if you still fall under 20 carbs a day?

    Our keto recipe guidelines call for a dish to have a max of 4% of calories from carbohydrates and this is higher, at 6%. Occasionally having a moderate low carb meal such as this is likely to be OK for most people when keeping an eye on your carb count across the day. You can read more at this link:
