Mango
Always tastes great as an taste in every food or drink
Plums
Grapes. They’re the best.
Apples. In the PNW it is hard to get good versions of other fruits. As they just don’t travel well.
It is hard to beat a good Mango or Peach in season though.
Tomatoes, or avocados
Both are amazing tasting very versatile, and go on a burger.
