Preheat oven to 350 degrees. In a bowl, combine dry ingredients, flour, sugar, salt, baking soda and walnuts. Set aside.
In a second bowl mix the vegetable oil, eggs, bananas, pineapple, vanilla and the coconut until thoroughly mixed. Fold into the dry ingredients.
Grease 2 large loaf pans (or 3 small). Bake for 50 to 60 minutes, stick a toothpick in and if it comes out clean it is done. Leave set until cool, then cut or freeze. To use after freezing, just let it thaw.
This freezes well. Tastes just as good as when it came out of the oven.
