Work lunches-inspiration wanted!

Throughout the summer, I found it easy to make tasty and interesting lunches each day. Now the days are colder, salad struggles to make the grade- the quality of salad ingredients is lacking (I'm looking at you expensive but substandard avocado!), and by midday, I'm looking for something warm to fill my belly. This is today's effort- boiled eggs, salad with offending avocado, a banana, and some natural yoghurt topped with toasted almonds, cinnamon and honey.  Will be delicious... but cold!
