In a Insta Pot or large pot bring your cabbage to a simmer and cook until just tender and pliable. Drain the water off and let it cool.
Get your precooked quinoa and butternut squash ready (I cook these on my prep day so I can use them throughout the week)
In a medium skillet sauté the ground turkey with the chopped onion, carrots, mushrooms and garlic until the meat is done. Add the quinoa, oregano, salt and pepper. Set it aside to cool.
In a 9x13 baking dish spoon 1 cup of the butternut squash into the bottom of the pan and spread it out to cover the bottom of the dish. Set it aside, it is ready for the cabbage rolls to be placed.
Assemble a leaf of cabbage onto a large cutting board, add two or three leaves of kale or spinach and scoop 1-2 tablespoons of the meat mixture, grate a little Romano cheese over it and roll it up until covered. Place it in your prepared 9x13 dish. Repeat until all the cabbage and filling is gone.
Use the remaining butternut squash to drizzle over the rolls and top with the shredded Romano cheese.
Bake for about 15-20 minutes until heated through.
