Prepare the peas by rinsing frozen peas thoroughly under cool running water and patting them dry to ensure crispness.

Combine dried peas, crumbled feta cheese, and freshly chopped mint in a large mixing bowl, and gently fold together.

Whisk together lemon juice, olive oil, and a pinch of salt in a separate bowl until well combined.

Drizzle the dressing over the pea mixture and gently toss to coat evenly.

Cover and let the salad sit at room temperature for at least 15 to 30 minutes to allow flavors to meld.

After marinating, give the salad a gentle toss and serve, optionally adding chopped nuts for crunch.
