Soak wheat berries overnight or at least 8 hours (if you don't have time for this step, cook the wheat berries for longer).
Bring a medium-large pot of salted water to boil and add the soaked wheat berries. Cook for 1 hour, slightly covered, stirring occasionally, until the wheat berries are cooked (they will be slightyl chewy even when tender). Drain and place in a medium salad bowl to cool.
Add chopped fruit/veggies, nuts/seeds, dried fruit and herbs and toss. Add olive oil and apple cider vinegar and toss again. Season with salt and pepper to taste.
