In a medium saucepan, bring water to a boil. Add rice, reduce heat to low, cover, and simmer for 15–18 minutes until water is absorbed and rice is tender. Let it sit covered for 5 minutes, then fluff with a fork.

In a mixing bowl, combine the cooked rice with mashed avocado, lime juice, lime zest, cilantro, and olive oil (if using).

Mix until creamy and well combined. Season with salt to taste.

Serve warm or at room temperature as a side dish.
