In a small saucepan, warm the brown rice syrup, cinnamon, salt, safflower oil and vanilla extract over medium low heat. Stir often until the mixture is smooth and combined well.
Combine the rolled oats, flaxseeds, walnuts and raisins in a large bowl. Pour the syrup mixture on top, and mix with a wooden spoon until evenly combined.
Coat a baking sheet with baking spray. Spread the granola evenly onto the baking sheet.
Bake for 10 minutes. Stir the oats well, then bake for another 10 minutes.
Remove from oven and allow to cool well before pouring granola into a bowl.
