Bring a large pot of water to a boil.
Remove the entire core of the cabbage with a knife. Immerse the head of cabbage in the boiling water for a few minutes. Peel off each leaf with tongs as soon as it's flexible. Set the leaves aside on a collander.
In a large bowl, combine all the ground meat, one onion diced, the rice, sliced scallions, chopped dill and parsley, a pinch of cumin and sea salt, and freshly ground pepper.
Remove the hard rib if any from the leaves with a knife. Place a spoonful of the stuffing mixture in the middle of each cabbage leaf, and wrap into rolls.
Add a tablespoon of olive oil in a large pot over medium high heat. Saute the second diced onion for a few minutes. (this onion can also just be sliced. As soon as the onion has softened, place a handfull of fresh parsley son top. You can add some leftover cabbage leaves on top (optional). Transfer the cabbage rolls to the pot in layers next to one another, and cover with a plate to not unwrap while cooking.
Pour enough water to cover the cabbage rolls, and add 1/3 cup olive oil.
Cover and simmer in low for 60 minutes. Remove from heat, uncover and let food sit for 10 minutes to cool the broth.
