This is a very large meal for one or a starter for two (with 6g net carbs each).
Choose the smallest Lolito Vulgaris squid. Once cooked it will be either tender (if bought fresh) or crunchy (if previously frozen). Other varieties, or overcooking, will result in a rubbery, chewy texture that is quite unpleasant.
You can buy ready cauliflower 'rice' or make your own: just put a few fresh florets in a food processor or blender and pulse until crumbed, then repeat, a few florets at a time (too many at once will become pulp).
You can mix 70g double/heavy cream + 30g water to replace the 35% fat cream.
Any dry white wine will be fine if you don't have Prosecco.
