In a large bowl, whisk together lemon juice, olive oil, salt and pepper.
When rice is done cooking, add it to the bowl with the lemon juice and stir to combine and break up the rice. The lemon juice and olive oil will naturally separate, so whisk it again right before adding the rice if you see separation.
While the rice is still quite hot, add the feta cheese and stir to evenly distribute. Use your fingers to crumble any especially large chunks as you add them. The heat from the rice will melt the feta slightly, but it should still remain in visible chunks.
Tear or thinly slice the basil leaves and add them to the rice. Toss to combine.
Serve warm.
RECIPE NOTES
To chiffonade basil leaves, layer 6-8 leaves on top of each other, roll them into a log, and slice thinly across the log.
