Preheat your oven to 350°F (175°C).

In a mixing bowl, cream together the sugar and softened butter until well combined.

Add the eggs to the creamed mixture and beat until fluffy.

Toast the bread slices until golden brown, then crumble them into small pieces.

Stir the crushed pineapple with its juice and the crumbled bread into the creamed mixture, ensuring everything is well mixed.

Pour the mixture into a greased baking dish.

Bake in the preheated oven for 40 minutes, or until the top is golden brown and the pudding is set.

Serve warm and enjoy the tropical flavors.
