I'm the kinda girl who will say "I can't sleep, I'm going to make a sandwich". Then come back an hour later having raided her fridge to make a small stir fry. On this occasion using leftover cabbage and onion that didn't make it into a pickling jar, rice that was cooked over the weekend in chicken stock I made myself, a can of sardines, and a 2 ounce container of leftover salsa verde from takeout. Which turned out not terribly amazing, but not so bad at hitting the spot for now.
I just can't seem to help myself when it comes to random urges to throw ingredients together and see what happens.
