Preheat oven to 325°F; grease two rimmed cookie sheets. Mix first six ingredients together in a large bowl. Warm honey and then stir in oil and cinnamon. If using brown sugar dissolve it in ¼-cup water before adding to the oil, or use ¾-cup oil and omit water. Pour the sweetener mixture over the dry ingredients and mix thoroughly. Spread on baking sheets and bake about 30 minutes, stirring often. Watch closely at the end of baking time so granola does not become too dark. Cool, then break into chunks and store in airtight container.
