Preheat the oven to 350°F.
Lightly oil or coat an 8 x 8-inch baking pan or dish with nonstick cooking spray and set aside.
Place the oats, shredded wheat, walnuts, dried fruit, cinnamon, and salt in the bowl of a food processor and pulse until the mixture is finely chopped (the fruit should be the size of a dried pea or lentil).
Whisk together the eggs, honey, and vanilla in a large bowl until well blended. Add the oat mixture and chocolate chips and stir to combine.
Spread the mixture evenly in the prepared pan, and flatten gently with the back of a spoon or rubber spatula.
Bake about 18 minutes, or until the edges turn golden brown. Let cool completely in pan before slicing into 12, 2 x 2 1/2-inch bars.
Note: These bars freeze really well. If you have leftovers, wrap individual portions in plastic baggies or aluminum foil and freeze.
