I don't want to waste food!
I hate being wasteful, but I am also nuerotic about freshness or when food isn't good anymore. So if I made a roast beef or chicken and its been in the fridge for 3 days (since no one ate it) do I toss it or still use it? What is everyone's time limit on keeping food before throwing it out? Also, other perishables such as lunch meat, cheese, pasta?
