Bring tea to a boil in a 3-qt. saucepan over medium-high heat; stir in rice and 1/2 tsp. salt. Cover, reduce heat to low, and simmer 20 minutes or until tea is absorbed and rice is tender.
Transfer rice to a large bowl, and let cool completely (about 30 minutes). Stir in tomatoes, green onions, parsley, mint, olive oil, lemon zest, lemon juice, 1/2 tsp. salt, and pepper. Cover and chill 1 hour.
