Preheat the oven to 180°C (356°F) with top and bottom heat.
In a large bowl, mix the oatmeal, almonds, cinnamon, and salt. In a saucepan, melt the coconut oil on low heat for about 2-3 minutes until completely liquid. Stir in the honey. Pour the oil-honey mixture into the oatmeal mixture and stir until all ingredients are evenly coated. Line a baking sheet with parchment paper and spread the mixture in an even layer.
Bake for 10 minutes, then remove from oven and stir the muesli. Return to oven and bake for another 10-12 minutes. Watch closely in the final few minutes as the muesli can burn quickly. Remove from oven when lightly browned and let cool completely on the baking sheet for about 15-20 minutes.
Once cooled, store in an airtight container and use within 1-2 weeks.
