Agree that meal boxes are a good training step. We started using blue apron and after we got the hang of things, realized how much cheaper it would be to buy the ingredients on our own. The bottles of sauces can be pricey up front, but once you have a collection of them, cooking is easier and cheaper. Also, people are really impressed if you can impromptu make something without having to go out shopping.

I felt like a true adult when I decided to make hummus one day and just happened to have everything for it.
