Slice the already sliced bread down the middle, but not all the way, leave about 3/4 inches.
Take a bread knife and cut about a 1/8 to 1/4 inch piece of cheese (long ways) and gently spread it between the slit in the bread on one side, without breaking it apart, and then again on the other side. Of course, if the bread splits, don’t worry, you can just sandwich it and it tastes the same…I just like leaving an edge at the bottom in case you want to stand it up. If you are using a spread than spread about a tablespoon and a half of spread on each inner side.
Take about 6 slices of strawberry and push it down in the middle of the cheese/spread.
Whisk the eggs, heavy cream, milk, sugar, cinnamon, salt, and vanilla (if using) until well combined.
Dip the bread pieces into the mixture and turn so all sides have been soaked for several seconds in the liquid.
Heat a cast iron pan (or any pan) on medium, lay in one or two toasts at a time and cook for one minute, then turn and cook for about a minute on all sides. If you see the toast cooking too fast turn down your heat to low. You want to make sure the egg is cooked.
Plate and top with your favorite syrup, sprinkle with some powdered sugar and cinnamon, and serve with some whipped cream and additional berries. Don’t make too many cause you will want to eat it all!
