Preheat oven to 350°F (175°C).

Combine all-purpose flour, sugar, salt, and sugar in a large bowl.

Stir in chopped nuts.

In a separate bowl, whisk together beaten eggs, Crisco oil, mashed bananas, drained crushed pineapple, and vanilla extract.

Add the wet ingredients to the dry ingredients and mix until just combined.

Pour the batter into a greased and floured loaf pan.

Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.

Let cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
