Mix pineapple, eggs, sugar and flour together.Pour into agreased (8x8inch) baking dish. (I double the recipe and bake in 9x13" pan).
Toss bread cubes with melted butter. Place cubes on top of pineapple mixture. Bake at 3250 for 30 to 40 minutes, until browned. (If doubling recipe, bake 13x9" pan for about 45 minutes or until bread cubes are nicely browned.) Excellent when served with baked ham.
