In a large pan, heat the coconut oil over medium heat. Add the chopped onion, minced garlic, and grated ginger. Sauté until the onion becomes translucent.
Add the cauliflower rice to the pan and stir well to combine. Cook for about 5 minutes until the cauliflower rice is tender but still has a slight crunch. Season with curry powder, turmeric powder, cumin powder, salt, and pepper. Stir to evenly distribute the spices. Remove from heat and set aside.
In a separate large pot or deep skillet, heat the coconut oil over medium heat. Add the diced onion and minced garlic. Sauté until fragrant and slightly softened.
Add the sliced carrot, red bell pepper, and shiitake mushrooms to the pot. Stir-fry for a few minutes until the vegetables start to soften.
In a small bowl, whisk together the coconut milk, yellow Thai curry paste, soy sauce (or tamari), and maple syrup until well combined. Pour the mixture into the pot with the vegetables and stir to coat.
Reduce the heat to low and let the curry simmer for about 10-15 minutes, allowing the flavors to meld together. Stir occasionally.
Squeeze the lime juice into the curry and give it a final stir. Taste and adjust the seasoning if needed.
Serve the curry over the curry cauliflower rice. Garnish with fresh cilantro.
