Help improve tabouli that went wrong

I made a huge bowl of tabouli and it turned out terrible—maybe the olive oil was rancid or it was just way too much parsley for my taste (3 cups!) so I washed all the veggies off and took out most of the parsley. Now I’m left with a big bowl of cooked bulger wheat, tomatoes, chopped cucumber and bell pepper, and garbanzo beans. I would normally cook most of these ingredients but cooked cucumber sounds wrong. What can I do to fix this? It was expensive for all these ingredients and I don’t want it to go to waste. I’m vegetarian and eat cheese and dairy.
