I just had a tuna-rice-veg casserole for breakfast (I'm with SusanW on this - learned years ago that anything can be breakfast). It was nourishing, warm, but just ok on taste. Then I added Sriracha and sesame oil from the fridge door. Ka-boom! Great taste lift, even though the original dish had no inherently Asian flavors.
So, what else is luring in your fridge door or condiment section that you (and I) can use to liven up winter or fridge-clear-out dishes?
