To make these dolma, start by washing and drying the bell peppers. Once they're washed, slice the tops off of the peppers and discard them. Try to slice as little of the pepper off as possible, so that the top is removed but the pepper is still intact. Then, use your hands to gently scoop out the seeds.
Next, set the peppers aside and prepare the filling. Add the meat, rice, onion, parsley, garlic, tomato paste, cumin, cayenne pepper, paprika, sea salt, and black pepper and mix them to fully combine.
Then, fill each pepper with the mixture and place them into a dutch oven or large pot, with the cut sides facing up. Pour the broth and tomato sauce on top of the peppers.
Place the dutch oven or pot onto the stove and bring the mixture to a gentle boil. Once it's boiling, reduce the heat to low, and place a large dinner plate on top of the peppers, upside down.
Allow the peppers to cook for 45-60 minutes, until the bell peppers and rice are nice and tender.
Once they're done, transfer the dolma to a platter and season them again with sea salt and black pepper. Spoon the remaining sauce over the top of the dolma, and garnish with greek yogurt and more chopped parsley, if desired.
Finally, serve them and enjoy! These dolma can be stored in an airtight container, in the fridge, for up to one week.
