What to eat

HI there. I’ve been on the jab since May and my weight journey is going well. What’s not going well is eating healthy meals and gym motivation. I’m not worried about the gym part as once the weather cools I’ll be able to pick that back up but i am worried about healthy meals. Despite many attempts I’m a terrible cook so I was wondering what easy/quick/safe meals do you have for lunch/tea you can suggest for someone who is terrible in the kitchen and hates spending any time there. I’m ok with a healthy stir fry but getting bored of them. I think I’m about 2 months away before I stop with the jabs so want to fix this in this before then. I can do plain bland food and easily avoided sauces. i got into trouble due to processed food, chocolate and crisps etc as it’s much easier to grab them than trying to cook anything.
