Blueberry Oat Bars

Heat oven to 350ºF. Grease an 11×7-inch baking pan.

Combine oats, flour, maple syrup, walnuts, baking soda and salt. Add margarine, mixing until crumbly. Reserve 3/4 cup of the mixture; press remaining mixture onto the bottom of the prepared dish. Bake 10 minutes.

Meanwhile, combine blueberries, granulated sugar and 2 tablespoons water in a medium saucepan. Bring to a boil, simmer 2 minutes, uncovered, stirring occasionally. Combine remaining 1 tablespoon water, cornstarch, and lemon juice; mix well. Gradually stir into blueberry mixture; cook and stir about 30 seconds or until thickened.

Spread over partially baked base to within 1/4 inch of the edge; sprinkle with reserved oat mixture. Press topping down into blueberries slightly.

Bake 20 minutes or until topping is golden brown.

Cool on a wire rack; cut into bars. Store tightly covered.
