    I'm amazed at how delicious this very simple recipe came out. I'll use this practically instant sauce on other things as well.

    This is such an easy and tasty meal. Defiantly a meal for the whole family. Note. I did put to much cheese in. ?

    Can you use frozen broccoli?

  4. Can you use frozen broccoli?

    Hi Julie!

    Yes, you can! Frozen vegetables tend to release water, but this will evaporate while frying. Good luck!

    I don't use as much thyme as they say cause it will over power the whole meal if you aren't careful. I usually cut it in half and then it isn't as over powering and it still taste great

    I wasn't expecting the flavor to be this good! Delicious and easy to make! I will be making again! :)

    Does this have a breakdown of how many carbs fats and protein?
  8. Hi Michael!

    If you hover your mouse over the symbol for "Strict/Moderate/Liberal Low Carb" on the pictures for all our recipes then you will get the nutritional facts.

    The amount of displayed carbs is net carbs (Total amount of carbs - fiber).

    So you fry the broccoli and cauliflower from raw?
  10. Janet
    Can I substitute the leeks for something else?
  11. Debra
    Trying to get more information, I accidentally "reported" a couple of comments. Sorry about that. I was simply trying to found out how long the vegetables should be fried.
  12. Shelley Hill
    Hi, would the brocolli and cauliflower not be hard if your only frying it?
    Thanks

    Is ground sausage ok to use with this recipe?
  14. P & B
    This was absolutely delicious!!! We will make this again and again! Added mushrooms, spinach and no salt or pepper (because the sausages were well seasoned). YUM! Thank you!

    I used red pesto with soured cream instead of mustard, and added left over veg like greens, peppers and garlic. I also crushed a poppadom on top (as they are low in carbs) before I added the cheese to give it a little bit of a crunch, it was delicious and really filling.

    My sour cream always cuddles when I make this. Even when baking in the oven at 400 instead of 450. Is the temperature still too high? I'm still not quite used to cooking with so much dairy. Still tasty though!

    This is great but why 16 grams of carbs nothing in it has many

    How long do you fry the sausage and the veg for? Doesn't specify. Thanks!
  19. Andrea
    Probably from the broccoli and cauliflower. I haven't plugged it into my tracking app yet, but I bet the NET carbs are much lower.
  20. Mariane
    This is definitely one of my favorite recipes. Everybody likes it. I took it over to my neighbor's last week for a potluck meal and they loved it. I don't always add sausage and then I can eat it as a side with a bit of meat.
