Preheat the oven to 200 degrees (fan oven if you have one). Chop the nuts and place in a large bowl with the remaining dry ingredients. Place the oil, syrup, almond paste and vanilla in a small saucepan. Stir over medium heat and pour over the dry ingredients. Mix thoroughly and spread in a thin layer on (preferably) 2 baking sheets. Bake for 30 minutes, turning the trays halfway through.
Let the muesli set on the trays until it has reached room temperature, then remove from the tin. Pour it into an airtight jar.
Have fun giving it as a gift or eating it yourself!
