I'm going to say no since you clearly don''t have a clue, or you wouldn't be asking about carrying a gun in your purse. Normally I would tell you that it depends on your state and what kind of permit you need to get. However, you should not be carrying a gun at all, since it's pretty clear...
Invest in a crock pot. You'll be able to cook dinner while you're at work and then you'll have leftovers for lunch. I have found that everything I cook in a crock pot reheats well in a microwave, since it's so moist.
