Not sure if this is the right place, but I have tried googling and can't seem to find the relevant information. So I have been thinking of cooking and bringing it to office, and I have this question. I freeze pasta sauce to be used on a later date. I wish to bring it to work to eat for lunch. Is it safe to thaw it in the fridge at night, heat it up in the morning, put it into my bento box, bring it to work and then microwave it during lunch at my work place? Thanks!
