Steps
1. Slice the cucumber lengthwise and scoop out the seeds to create hollow 'boats'.
2. In a bowl, combine cooked quinoa, crumbled feta, chopped sun-dried tomatoes, olive oil, and parsley. Mix well.
3. Season the mixture with salt and pepper to taste.
4. Spoon the quinoa mixture evenly into the cucumber boats.
5. Serve immediately or chill for 10 minutes before serving for a refreshing taste.
