I live somewhere where I have access to dozens of restaurants within a 5 minute drive and I can order ahead to avoid waiting. Cooking really is not an activity I enjoy so I have no interest in practicing unless I have to. That is not to say I never have food at home. I regularly make healthy super smoothies, sandwiches loaded with greens, prepared salads, and whole grain cereals. I wouldn't consider that cooking though.

I'm not looking to invalidate the experience of anyone who is good at or enjoys cooking. Just sharing my opinion that this is one area that is very commonly recommended for saving money that I personally don't find worth my time.
