Bring a saucepan (at least 3 quarts) of water to a boil. Add a teaspoon of salt and the rice. Cook until the rice is just tender, with a tiny bit of bite in the center of the grain; 25 - 35 minutes. Drain.
Put the rice in a large bowl and pour over a few tablespoons of olive oil and the lemon juice. Season with more salt to taste.
Serve warm in bowls topped with mozzarella and garnished with your choice of fresh or roasted vegetables and greens.
