5 cups old-fashioned oats
Preheat oven to 325 degrees F. Mix oats, brown sugar, coconut, ground flax seed, cinnamon, and nutmeg together in a large bowl. Stir water, oil, and vanilla extract into the oat mixture; spread onto a baking sheet. Bake in preheated oven, stirring every 15 minutes, until golden brown and crunchy, about 1 hour; transfer to a bowl. Stir cranberries and almonds through the granola.
