Heat oven to 375° Fahrenheit. In a medium bowl, place cut apples and sprinkle with water and 1 ½ teaspoons Oregon Chai® and stir together. Place apples in an 8x8 pan or round pie dish. Place margarine in the bowl and stir in remaining Oregon Chai. Add oats, flour and brown sugar; stir until crumbly. Sprinkle over apples. Bake until golden brown and apples are tender, about 25-30 minutes. Serve with a dollop of whipped cream or a scoop of vanilla ice cream.
