Preheat the oven to 350 degrees F.
Toss the oats, coconut, and almonds together in a large bowl. Whisk together the oil and honey in a small bowl. Pour the liquids over the oat mixture and stir with a wooden spoon until all the oats and nuts are coated. Pour onto a 13 by 18 by 1-inch sheet pan. Bake, stirring occasionally with a spatula, until the mixture turns a nice, even, golden brown, about 45 minutes.
