Thinly slice the bread loaf into 10 slices, around 1.5 oz each. Thinly slice the banana.
Whisk the chickpea flour, almond milk, cinnamon and vanilla extract in a bowl.
With 5 of the bread slices, spread 1 TBSP of the peanut butter onto each. Add the banana slices on top. Place the remaining 5 slices on top.
Heat a skillet over medium low heat, coating with cooking spray. Carefully dip the sandwiches into the almond milk mixture, coating each side of the sandwiches.
Add a couple of the sandwiches to the pan, cooking for about 3 minutes on each side, or until the bread turns golden brown. Repeat with the remaining sandwiches.
Meanwhile, combine the dark chocolate chips, maple syrup and cinnamon in a small saucepan over low heat. Stir often as the mixture melts.
Once French toast is done cooking, transfer to plates, and drizzle the chocolate syrup on top. Add sliced strawberries, if using, and enjoy while it's warm!
