Preheat oven to 350 degrees.
Spread oats, wheat germ and nuts on a baking sheet; bake, stirring occasionally, for 15 to 18 minutes, until lightly browned and fragrant.
Reduce oven temperature to 325 degrees. Line an 11x7-inch baking pan with foil. Lightly oil or coat with nonstick spray.
In a large bowl, whisk together egg, egg white, brown sugar, oil, cinnamon, salt and vanilla extract. Stir in toasted oat mixture, dried cranberries and flour.
Spread in prepared pan and bake for 30 to 35 minutes, or until golden brown. Cool completely; cut into 16 bars with a lightly oiled knife.
