Prepare pearl couscous according to package directions.
In medium bowl, toss shrimp with seasoned salt.
In large saucepan over medium-high heat, heat 1 tablespoon oil. Add shrimp and cook 5 minutes. If necessary, cook in batches to avoid overcrowding pan.

In large bowl, combine pearl couscous, shrimp, chickpeas, cucumbers, tomatoes, basil, red onion, dill, lemon juice and remaining olive oil. Toss to combine. Garnish with feta.
