Hally, sometimes I just pour some cous cous into my casserole if it's a little too runny. It absorbs the excess liquid and just adds to a little body to the meal. You don't even notice it in the end.
Tonight I'm home alone as my OH has gone off to the Adelaide Crows game. I was supposed to be having left-over roast pork and veggies for dinner tonight, but I'm thinking I might have pancakes (you can eat what you want when you're home alone )
