Cook rice according to package directions.

Preheat oven to 350°F (175°C).

Dice green onions and pimientos.

Melt butter in a skillet over medium heat.

Sauté diced green onions and pimientos in the melted butter until softened.

In a large bowl, combine the cooked rice, sautéed green onions and pimientos, well-beaten eggs, salt, and drained bean sprouts.

Grease a round ring mold thoroughly.

Pour the rice mixture into the prepared ring mold.

Place the ring mold in a large baking or roasting pan.

Fill the baking pan with 1 inch of water to create a water bath.

Bake in the preheated oven for about 20 minutes, or until the rice ring is set.

Remove from oven and let cool slightly.

Invert the ring mold onto a serving plate to unmold the rice ring.

Serve hot.
