if you are strictly low carbing two websites you will find invaluable are
Zero carb megastore and Avidlite as you can get all sorts of zero and low carb substitutes including bread, rolls, (Bread is 2.5 g carb per slice) soups, cakes, baking mixes, sweets, crackers and biscuits.
And they will be full of additives,and processed within an inch of their lives. Better to train yourself not to eat those things. Stick to real food...far more healthy.
have you tried 'cauliflower rice' by the way grate cauli and steam for 5 mins as half teaspoon of turmeric, some cumin and a little oil and toss well great with curry
I was thinking cauli mash, I'll have to google a recipe. Parsnips are a no-no on low carb as they are almost as high as a potato. Would any low carb veg do, if it was cooked so it was soft enough to mash/become mush lol - but then overcooking takes all the goodness out, or is that old wives tales? I can also use fresh cream??
Try putting cornflakes thgrough food processor and use as breadcrumbs on top of your pie.Is also good if mixed with paprika or any herb or spice you prefer.
