Preheat the oven to 325 degrees F. Spray a 13-by-9-inch metal baking pan with cooking spray. Line the pan with foil, with the ends extending 2 inches over the short sides of the pan. Spray the foil with cooking spray.
In a glass pie plate
, spread out the oats and microwave on high in 1-minute increments until fragrant and golden, stirring occasionally, 4 to 5 minutes. Cool to room temperature.
In a large bowl, combine the cooled oats, cranberries, walnuts, wheat germ
, brown sugar, cinnamon
and salt. Stir in the honey, oil and egg
whites until well mixed. Transfer to the prepared pan. Use a wet hand to press the mixture into an even layer.
Bake until dark golden, about 35 minutes. Cool in the pan on a wire rack.
When cool, use the foil to transfer to a cutting board. Cut lengthwise into 6 strips, and then cut each strip crosswise into quarters. (You should have roughly 3 1/4-by-1 1/2-inch bars.) Bars can be stored in a tightly sealed container at room temperature up to 1 week, or in the freezer up to 1 month.
