1Bring a large saucepan of heavily salted water to a boil over high heat and cook the pasta until al dente, about 8 minutes. Drain and rinse under cold water until cool. Drain the pasta well and transfer it to a large, nonreactive bowl.
2Add the tomatoes, cucumbers, pine nuts, olive oil, basil, parsley, scallions, lemon zest, and lemon juice and toss to combine. Taste and season with salt, pepper, and additional lemon juice as needed. Serve chilled or at room temperature.
