Preheat your oven to 425℉. Line a large rimmed baking sheet with parchment paper.
Keep your cabbage core INTACT, slice your cabbage in half first then into thick slices - ending up with 6-7 slices. Place them on your baking tray and brush both sides of each slice with olive oil. Season with salt to taste and sprinkle with the seasonings listed to taste. Don't be shy - give it some color! Roast in your oven for 30-35 minutes or until golden.
Ground Meat Topping:
In a large skillet, heat your oil and then saute your onion for 2 minutes. Add in the ground meat and using a wooden spoon break everything up until no longer pink and cooked through. Season with salt, and all the seasonings listed, generously. Again, give the meat some color. Use this to top the roasted cabbage slices and top with the cheese and pop back into the oven until melted - about 5 minutes.
Assembly:
If you're using the beans, simply top the cooked cabbage steaks equally with some beans, covering the cabbage and then top with the shredded cheese. Pop back into the oven until the cheese has melted - 5 minutes. Remove from oven and top with tomatoes, avocado and cilantro!
Crema:
Whisk together the ingredients and use milk to thin out the sauce to your desired consistency. Mine took about 3 tbs to thin out. You can leave out the milk too.
