Preheat the oven to 300 degrees. In a large bowl, stir together the dry rolled oats, shredded coconut, and sliced almonds.
In a small pot, combine the oil, brown sugar, honey, salt, vanilla extract, cocoa powder, and water. Heat over a medium-low flame and stir until the sugar is dissolved (about 5 minutes).
Pour the chocolate mixture over the oats. Stir very well until everything is evenly coated. Cover a baking sheet with foil and pour the oat mixture out onto it. Spread the mixture into a layer about 1/2 inch thick. Bake in the preheated oven for 45 minutes.
When the granola comes out of the oven, take a spatula and press it down to compress it. Allow the granola to completely cool. Once cooled, break into chunks and serve or store in an air-tight container at room temperature.
