It is expensive if you are feeding a family. For me it's cheaper to eat fast food and be done. When I have cooked something I usually end up throwing away the leftovers because no one eats it because I am hardly home these days. There is always food around at work too
Our left overs are my lunches at work, so that is a plus. However I do get sick of eating good healthy meals at work so I do have my Hot Pockets, etc.... that I occasionally bring to work.
