Preheat oven to 350 degrees Fahrenheit.

Grease an 8-inch square glass baking dish with butter or cooking spray.

Assemble 4 sandwiches, each with 2 slices of white bread, 1 slice of American cheese, and 1 slice of boiled ham.

Place the assembled sandwiches in the prepared baking dish.

In a mixing bowl, beat together the large eggs, lowfat milk, and vanilla extract until well combined.

Pour the egg mixture evenly over the sandwiches in the baking dish.

Sprinkle a light dusting of nutmeg over the top of the strata.

Allow the strata to stand for 5 minutes to allow the bread to soak up the egg mixture.

Place the baking dish inside a larger pan and fill the pan with approximately 1 inch of water to create a water bath.

Bake in the preheated oven at 350 degrees Fahrenheit for about 30 minutes, or until the custard is set and the top is lightly browned.

Remove the strata from the oven and water bath. Let it cool slightly before serving.

Garnish each serving with 1 teaspoon of jelly before serving.
