Hi,
Good of you to ask advice when recognising you experience problems. I’m not a professional cook, but I can cook well enough for it to be okay for other people. The problem in this case being that I learned by doing, trial and error and over a period of 15+ years now. Which means I can’t give steps to follow or the advice that will trigger improvement. Since I don’t know what your knowledge or experience entails, I’ll share the broadest of advice. (Even though NT people would find it too basic and might get offended. This is not my intention and I hope you will ignore every part which you deem redundant )
To summarize, a.k.a. TL;DR:
I hope you can find a bit of use in some of this advice.
My go too recipe is cooking (not boiling) garlic, onion, bell pepper and another vegatable in a pan (wok?). Depending on spices or sauce I serve it with rice, noodles/ramen or pasta. “Another vegetable” can change per day too switch things up and not eat the same thing everyday. I love zucchini (though dislike the English word for it), celery and/or carrots as the extra vegetable. But anything can work!
Also, I’ve found a funny cookbook which may help. It’s full of dark humour. Not to be taken too seriously, but it has helped me with the confidence too cook what I need. The premise of the book is “you need to eat something, otherwise you die” and it acknowledges that cooking can be a hassle and can cost a lot of energy. I’ll look up the pdf and edit this or add an extra comment.
This is the funny cookbook. The author made it free to download. https://traumbooks.itch.io/the-sad-bastard-cookbook
