In a large skillet or pot, heat the coconut oil over medium heat. Once melted, add the sliced onion and sauté for about 5 minutes until translucent. Stir in the minced garlic and ginger and cook for another 1-2 minutes until fragrant.
Add the Thai red curry paste and red pepper flakes to the onion mixture. Stir well and cook for about 2 minutes to toast the spices.
Incorporate the carrots and red bell peppers, stirring to coat with the spice mixture. Cook for about 5 minutes to soften the vegetables.
Pour in the light coconut milk and stir to blend. Bring to a gentle simmer, then reduce heat to low.
Add the coconut sugar, chickpeas, soy sauce, and rice vinegar. Stir well and let simmer for about 15-20 minutes.
In the last few minutes of cooking, add the frozen peas. Stir and let heat through. Taste and adjust seasoning as necessary.
Serve the curry over prepared brown rice or quinoa, garnished with chopped cilantro.
