@Alansbigplate you mentioned in the previous thread about easy recipes. I had quite some time when through various reasons I'd stopped cooking for myself. One reason was because of low energy and mood I did not want to deal with the mess and washing up.
One thing that helped me was getting one (and later another) of these
Amazon product
I found various microwave meals for one online. I've done mushroom risotto, French onion soup, 'stir fried' chinese noodles and lots more. Other thing that helped was having pre prepared veg such as sliced onions, soffrito mix and mushrooms in the freezer so I could just use what I needed. Frozen herbs that you could just take a pinch of added extra zing.
It's also very handy to be able to eat out of the cooking vessel!
