Place the walnuts in a food processor and pulse five to six times until the walnuts are finely chopped. Place in a shallow dish large enough to hold a slice of bread.
Make the custard by whisking together the flaxmeal, whole wheat flour, soymilk, vanilla extract and maple syrup in another shallow dish large enough to hold the slice of bread.
Dip the slices of bread one by one in the custard and coat on either side. I let them soak about 20-30 seconds on each side.
Dip the slice of bread into the walnuts and shake off any excess.
Heat a skillet and coat with a thin layer of vegan butter or spray on some cooking spray.
Serve hot with a drizzle of maple syrup.
