Maybe a basic tomato sauce, without the carrots and celery (didn't have them) but what about adding some dried Porcini mushrooms? Porcini are a back pocket trick of mine to add depth to sauces, soups, and marinades.
After reconstituting the mushrooms in boiling water, I came to the task of having to cut them, something I take pleasure in when I have time and a sleeping baby. Plunging my fingers into a hot bowl of mushroom broth, retrieving some slimy, flaccid mushroom pieces and cutting them didn't appeal, so I remembered the handy pair of shears in my drawer, and all for which they are useful.
By using scissors instead of a knife, the cutting can be done quickly, and without removing the mushrooms from the bowl. It was done in under ten seconds. Including the photography (obviously - apologies for the camera phone shot.)
For a great list of other things you can use kitchen shears for, see Nina's ode to her Messermeister Kitchen Shears where she lists eight more kitchen uses for scissors.
