Rinse the Grains: Start by rinsing the brown rice and quinoa separately under cold water using a fine-mesh strainer. This step removes any residual dust and helps reduce the natural bitterness of quinoa.
Boil Water or Broth: In a medium pot, bring 4 cups of water or vegetable broth to a boil. Adding broth enhances the flavor of the grains.
Cook the Brown Rice: Add the brown rice to the boiling water or broth, reduce the heat to low, cover the pot, and let it simmer for 20 minutes.
Add Quinoa: After 20 minutes, add the rinsed quinoa to the pot. Stir gently to combine, cover, and continue to simmer for another 20 minutes or until both the rice and quinoa are tender and the liquid is absorbed.
Fluff and Serve: Remove the pot from heat and let it sit, covered, for 5 minutes. Fluff the grains with a fork, drizzle with olive oil, and season with salt if desired. Garnish with fresh herbs before serving.
