How to Make It
Bring a large pot of salted water to boil. Fill and large bowl with ice water and set aside.
Add the corn to the boiling water. Boil for 1 minute. Drain, quickly rinse under cold water, and put in the ice bath until fully cooled off. Drain.
In a large bowl, combine the corn, cucumber, carrot, feta cheese, olive oil, lemon zest, and lemon juice. Season with salt and pepper. Chill and serve.
