Blend the almonds into coarse pieces, and place along with the sultanas and oats on a baking tray. Bake for 5 minutes and stir around, then continue baking for another 5 minutes.
Meanwhile melt the butter, honey and vanilla in a saucepan, over medium heat. Let it boil an extra 2 minutes.
When the oat mixture is ready, tip into a glass bowl, and mix in the butter-honey. Stir until combined, and then pour into a greased casserole.
Press down until the surface is firm. This can take a few minutes, and the mixture should still be hot (I had to use a spatula, which really helped).
Chop up the almonds in halves and press down into the muesli.
Leave to cool completely and then add the chocolate chips (you don’t want them to melt and lose shape) Sprinkle with a bit of salt, if you prefer more of a salty-sweet taste.
