Like @Resurgram I have an Actifry and I also have an Instant Pot - great tools for cooking from scratch.
What I found invaluable was the low carb/keto web sites for delicious recipes and for the most part family eat what I eat as mostly they don't know what it is as it looks so "normal".
The following are great sites
https://www.ibreatheimhungry.com/
Diet doctor.com
https://www.ditchthecarbs.com/recipes/
http://healthylivinginbodyandmind.com/24-fathead-cheese-dough-recipes-low-carb-gluten-free/
Healthy Living site is great in itself but I've copied the main link for the Fathead recipes. I have given my family Fathead pizza and they actually prefer it.

I started by doing a two week low carb challenge to get into the way of things. There's one one diet doctor and another on this site. I used diet doctor as it did everything - shopping lists the lot.
As a spaghetti substitute I use oomi noodles which I get in Tesco. Lidl high protein rolls are very popular as it the new Hovis lower carb seeded bread.
A lot depends on what you can tolerate by way of carbs as we're all different. You won't find the answer to that without a meter and testing strips. For example , some people can eat porridge but loads can't (myself included and I love it). Even the butternut squash in the above recipe would be too many carbs for me but will be fine for others.
It all seems very confusing but once you get into the way of it then you wonder why you worried about it.
By the way excellent results so far.
