This had a chewy inner texture and a nice crunchy crust. I used half sugar and half Splenda. I think it needs a little spice, such as nutmeg or cinnamon, and maybe some chopped walnuts. I think orange juice would work also if you don't have pineapple juice handy.
I used 1/2 cup sweetened coconut, 1/2 cup of Splenda, 1/2 cup pineapple juice and 1/2 cup pineapple chunks. This smelled very much like banana bread when it was done baking, though it didn't taste very strongly of either banana or pineapple. I prefer sweeter breads, and found 1/2 cup sweetener wasn't enough. The texture was a little chewy, probably because there's no oil in this. Otherwise very good - if I try to make it again, I may try to flavor it a little more.
