Dice the cucumber; drain and rinse chickpeas. Toss both into a large mixing bowl along with feta, oil, chopped dill, and pepper. Stir to fully coat.
Cut bell pepper into slices, and pineapple into chunks.
Serve cucumber salad with pepper slices, crackers, hummus, and pineapple on the side. If packing to-go, be sure the crackers are kept separate to prevent them from turning soggy.
