Preheat your oven to 375°F (190°C).
Slice the bell peppers in half lengthwise and carefully remove the seeds and white membranes.
Heat the extra virgin olive oil in a large skillet over medium-high heat.
Add the ground turkey to the skillet and cook until fully browned, using a spatula to break it into small crumbles.
Stir in the cauliflower rice, tomato paste, garlic powder, onion powder, dried oregano, sea salt, and black pepper.
Cook the mixture for 3-4 minutes until the cauliflower rice is slightly softened and the flavors are well combined.
Arrange the pepper halves in a baking dish and fill each cavity generously with the turkey and cauliflower rice mixture.
Pour the water into the bottom of the baking dish to create steam, which keeps the peppers moist.
Cover the dish tightly with foil and bake for 25 minutes.
Remove the foil and continue to bake for another 5-10 minutes until the peppers are tender and the edges are slightly charred.
Garnish with fresh chopped parsley before serving hot.
