Preheat oven to 350 degrees.

Prepare the cabbage leaves.

Wash the cabbage then place the cabbage in the microwave for 6 minutes. The leaves will be tender and perfect for rolling. Optional: you can also blanch the leaves for 1-2 minutes in boiling water then cool in an ice bath.

Cut out as much of the core as you can from the bottom of the cabbage, then carefully separate the leaves from the head. You will need 8-10 leaves for this recipe.

Chop some of the remaining leaves to make 1 cup of chopped cabbage and reserve.

Mix the diced Boca Burgers with the cooked rice then add salt and pepper.

Divide this mixture into 8-10 cylinder shapes. Place a cylinder of filling near the bottom of a cabbage leaf. Begin to roll it up, folding both sides over the filling, and finish rolling to enclose the filling, like an eggroll. Continue, filling and rolling all the cabbage leaves.

Meanwhile, over medium heat, melt the butter in a large saucepan. Sauté the diced onion until soft and golden. Add the garlic and saute for 2 more minutes, then add the reserved chopped cabbage and sauté briefly.

Add the tomato sauce, apple cider vinegar, brown sugar, salt and pepper to taste, and stir to combine. Bring to a boil, then lower and simmer for 5 minutes.

Line the bottom of a 13 x 9  pan with a layer of sauce. Place cabbage rolls, seam side down, on top of sauce.

Top cabbage rolls with remaining sauce then cover the whole pan with tin foil.

Bake for 30 minutes then serve hot with sauce ladled on top.
