DIRECTIONS

Process oats in a food processor until finely ground. Place in a bowl; add the flour, sugar, lemon peel, baking powder and salt. Slowly add oil, stirring until mixture resembles coarse crumbs. Combine milk and vanilla; stir into flour mixture, a tablespoon at a time, until mixture forms a ball.
    Turn onto a floured surface; knead 7-8 times. Place pastry between sheets of waxed paper; roll out to fit a 9-in. fluted tart pan with removable bottom. Grease the tart pan; gently press pastry into pan. Line pastry shell with a double thickness of heavy-duty foil. Bake at 350° for 12 minutes. Remove foil; bake 8-12 minutes longer or until lightly browned. Cool on a wire rack.
    For filling, combine 1 cup strawberries, rhubarb, sugar and lemon peel in a large saucepan. Let stand for 30 minutes. Cook and stir over medium-low heat for 8-10 minutes or until rhubarb is tender but retains shape. Combine cornstarch and water until smooth; stir into fruit mixture. Bring to a boil; cook and stir for 2 minutes or until thickened. Pour into a bowl; cover surface with waxed paper. Refrigerate for 1-2 hours.
    Just before serving, spread filling into crust. Arrange remaining strawberries on top. Brush with jelly. Yield: 12 servings.
