Making yogurt is pretty easy if you have somewhere warm to leave it (airing cupboard, instant pot, we have a range cooker with a hotplate and leave it on the lid of that overnight.
Yes also to stick blender mayo, that's pretty well the only condiment I use now.
I make sourdough bread every now and then, it is a 2-3 day process but minimal time taken once you have got your starter established. After the first day I slice it up and freeze it as it dried out easily. I also make soft white bread rolls at the weekend.
I've cut out loads of it in the last 6 months, however my late teen DCs and DH aren't bothered and as we often cook separately now (we all come in from work/college at different times, go out a lot in the evenings and have quite varied tastes) they still use a lot more UPFs than me, including wraps - they don't like the crosta mollica ones as they are too thick and I tend to agree, homemade are easy but go crunchy very quickly.
We all drink diet coke too, there is nothing quite like it (unfortunately the stevia version is rank). I am limiting myself to the odd one in the pub and having sparkling mineral water instead as much as possible.
