Preheat oven to 375 degrees F.
In a 9x13 baking dish, place the halved and seeded peppers, cavity-side up.
Fill the peppers halfway with pulled pork. Top the pulled pork with chopped tomatoes and sliced green onions.
If using an immersion blender, add the tomatoes, cumin, salt, pepper, cream (optional), garlic, and cilantro to a vessel and blend until combined.
Spoon the mixture over the pulled-pork-stuffed peppers. Cover the baking dish and bake for 30 minutes.
Remove the peppers from the oven and, using a knife, insert it into the side to test for tenderness. If the peppers are tender, sprinkle the cheese on top and return them to the oven for 10 minutes, or until the cheese is melted.
Top with sliced green onions and serve.
