When I have yoghurt, I like to make bircher muesli.
Weekday breakfasts can be frantic around here. Bircher muesli is great because I prepare it the night before, and it's disgustingly healthy. Oats and yoghurt are both considered 'super foods', with more than their fair share of nutritional goodness. Cinnamon is thought to moderate blood-sugar levels, and sultanas have fibre and (I think) anti-oxidants. We'll just ignore the massive amount of honey that Ryan likes to add...Kazari's Bircher Muesli
The night before: Grate an apple. Add about a cup of quick-oats, twice as much thick plain yoghurt, a handful of raisins or sultanas and half a teaspoon of cinnamon. Stir until all the oats are wet, and everything is well combined. Store in the fridge overnight, in a covered container. Try to choose a container with as little air as possible (I used glad wrap over a bowl, squished down to get the air out). It doesn't really matter, but it helps keep the apple from discolouring.
In the morning: Scoop out some muesli, slather with honey, and enjoy as much as you can before leaving for work.
Of course, the proportions in this are pretty arbitrary. As are the ingredients - any dried fruit works well, and you can substitue orange juice for the yoghurt if you really want to.
