Heat coconut oil in a large skillet over medium-high heat. Season pork with salt, brown in batches, 4–5 minutes per side. Set aside.
In the same skillet, sauté onion 5 minutes until softened.
Add garlic and ginger, cook 1 minute until fragrant.
Stir in curry powder, cook 1 minute more.
Add tomatoes, cook 4 minutes until they break down.
Pour in coconut milk, return pork to the skillet, and bring to a simmer.
Cover and cook 15–18 minutes until the pork is tender and the sauce has thickened.
Season with salt, top with cilantro, and serve hot.
