I have to share this soup tip which has revolutionised my office lunches. It is, simply, freezing the soup in silicone muffin moulds and bringing in just the right amount (3 cubes) to have for lunch. If you make a couple of large batches of soup over the weekend you can have healthy, comforting food on tap for the entire week and beyond.
I use this recipe for the filling - , Double the recipe made 2 and muffin pans of quiches. Bake for 30 min at 350 deg. Don't need to oil in between all the filo pastry sheets. Can add sprinkle of parmesan on top.
