Healthy foods you like?

Hello. I hope you're having a good week wherever you are in the world. If not, please know I'll be thinking about you and hoping things get better.

I am currently trying to make a change. I want to become healthy, but my family cultured a habit of eating out. My health is not that great and it could be because of my diet. I don't know much about cooking, so I am hoping the kind community here could help.

My family isn't huge, but our kitchen is small and hard to cook in large quantities to last the week.

I am wondering if anyone knows any healthy recipes for a starter cook, or perhaps healthy snacks to make for a family that loves sugar. We already have an array of fruit, but that doesn't always replace a meal.

Thank you very much.
