The only left overs we do is roast & corned beef. Everything else will just sit there and grow legs unless I throw it out.
What I do with my leftovers is slice them really small or shred them, and then I make a rice bowl and put them as toppings. My family really likes rice toppings. If can't do anything about it anymore because of lack of creativity, I give it to my brother's dog. She really likes leftovers.
leftovers are usually sent with hubby to work. If he's not crazy about eating something the next day, I'll warm it up for myself (or the tot) for lunch. Very seldom do they last more than a couple of days.
I take vegetables and throw them in a container in the freezer. When there are enough of them, I make soup.
