Whisk together the eggs, heavy cream, cinnamon, sugar, and vanilla. Set aside and prepare sandwiches.
Put together sandwiches with just bread and cheddar cheese. Cut the crusts off.
Heat a skillet with butter and gently dip the sandwiches in the French toast batter. Make sure to coat both sides. Drop into hot skillet and let sear on both sides. Keep warm in the oven until it is time to serve.
To serve, simmer Wild Blueberries and maple syrup in a saucepan for 15 minutes until reduced. Drizzle over warm French toast and enjoy!
