Whisk the egg, milk, orange juice, cinnamon, vanilla extract and salt in a bowl.
Dip bread (one at a time) into egg wash. Cook both toasts on a nonstick pan sprayed with cooking oil spray until browned on both sides. Remove from pan.
Syrup:
In the same pan, add the honey, water, sweetener/sugar, orange juice and cinnamon until it thickens like a syrup (about 1 minute).
Remove from heat and drizzle over French toast.
Sprinkle the pistachios and walnuts over the toasts, and optional cinnamon.
