It's not that hard and can be a mindfulness exercise with the washing, cutting and other prep, and then cook it and smells delicious and enjoy the food when it's ready. It can be as healthy as you want. Ina Garten videos/books explain well and she's like a kind and helpful aunt! Mr. Money Mustache also has some good advice on food and nutrition and cutting costs too.

Stay under 25 g added sugars a day, have them after/with fiber, good fats and proteins to slow the sugar hit to the brain and liver. Check fasting insulin and C-reactive protein along with the usual checks to look for metabolic and inflammatory issues earlier. Homa-ir and TG/HDL are useful to check your health for your gender and age, before you need treatment for something. You can eat great, spend less and be healthier!
