In a large bowl stir together oatmeal, bran and walnuts. In small microwaveable bowl, combine honey and vanilla; microwave on high for about 20 seconds or more until more runny. Stir to mix; pour over dry ingredients and toss to coat well. Spread evenly in large shallow baking pan and bake in 300ºF oven for about 30 minutes, or until golden, stirring two or three times. Cool completely; it will crisp as it cools. Stir in raisins or dried fruit; store in airtight container.
