This is what I do - make a big pot of chili or soup for the week. But I recognize that this might not work for everyone. At my work there’s a conveniently located fridge and microwave, and I can eat in my office with the door shut for a quiet meal. If any of those things weren’t there it might not be worth it.
I also enjoy cooking, and don’t mind spending time making my meal for the week. If the prep work was a real chore then it’d be much more tempting to buy something premade every day.
