Toss the cauliflower florets into a drizzle of olive oil and season with salt and pepper. Put them on a baking sheet and roast for 40 minutes or until the cauliflower is brown and tender.
Meanwhile, wash the grains.
Bring water to a boil and add grains and 1 teaspoon of sea salt and garlic.
Reduce heat to low and simmer covered for 20 minutes until grains are cooked and water is absorbed.
Turn the heat off and let sit, covered for 5-10 minutes.
Add the cauliflower, umeboshi vinegar, and a bit more olive oil.
Garnish with chopped parsley and serve.
Notes
For extra rich and delicious mash, roast garlic cloves in olive oil over low heat while the grains cook.
