Heat a saucepan over medium heat. Add oil, then sauté garlic and ginger for 1–2 minutes.
Stir in turmeric and curry powder. Cook for 30 seconds until fragrant.
Add water, coconut milk, and oats. Bring to a boil, then reduce to a simmer.
Simmer for 8–10 minutes, stirring occasionally, until oats are soft and creamy.
Add salt, pepper, red pepper flakes, and nutritional yeast (if using).
Stir in chickpeas or green peas if desired. Cook for another 2 minutes.
Serve hot, topped with cilantro, scallions, or toasted coconut.
