Rinse 1 cup of millet under cold water. In a medium pot, combine the rinsed millet with 3 cups of water and a pinch of salt. Bring to a boil over medium heat.
Once boiling, reduce the heat to low, cover, and let it simmer for about 20-25 minutes, or until the millet is tender and the water is absorbed. Remove from heat and let it sit covered for another 5 minutes.
While the millet is cooking, prepare the romesco sauce. In a blender or food processor, combine 1 cup of roasted red peppers, ½ cup of toasted almonds or hazelnuts, 2 cloves of garlic, 1 tablespoon of red wine vinegar, and a pinch of salt and pepper. Blend until smooth. Adjust the seasoning as needed.
In a dry skillet over medium heat, toast ¼ cup of sunflower seeds for about 5 minutes, stirring frequently until golden and fragrant. Set aside.
Fluff the cooked millet with a fork and transfer it to a serving bowl. Pour the romesco sauce over the top, and gently mix until the millet is well coated.
Sprinkle the toasted sunflower seeds and fresh parsley over the dish. Drizzle with a bit of olive oil for an extra layer of flavor.
