Prep: Chop tomato, cucumber, pepper, onion, and olives. Add them to a medium bowl along with olive oil, pepper, and salt. Toss to evenly combine.
Toast: Add pine nuts to a small saute pan and set over medium heat on the stove. Cook, watching closely, until pine nuts turn golden brown.
Assemble: Spread hummus onto a large platter or serving plate. Top with veggie mixture, toasted pine nuts, and feta cheese. Serve immediately with pita chips or crackers.
Notes
To make ahead, complete steps 1 and 2 in advance, storing the veggies, pine nuts, hummus, and feta cheese separately until right before serving.
