Cabbage rolls in lemon sauce

For 4 people
1 large savoy cabbage
2 medium potatoes
4 yellow onions
2 tablespoons cream or milk (soy or oat)
1 lemon
turmeric
salt
pepper

Remove a portion of the outer leaves from the cabbage that you will be using as wrappers.
Boil them and set aside.
Cut the rest of the cabbage into strips, potatoes into small cubes and chopped onions.
Brown in skillet and when it dries, add a glass of water, cover with a lid and cook until it softens everything and the water dries.
At the end add salt and pepper to taste.
Then prepare with this mixture the rolls, closing them with a stizzicadenti.
For the sauce, chop the other onions and fry, add the juice of three lemons and let the other fire 5 minutes towards the end add the cream (or even the oat milk), turmeric and salt.
Puree in a food processor to obtain a creamy sauce not too dense.
Place the rolls on a baking sheet, cover with the sauce and then toss them in the oven at medium heat for 5-10 minutes and serve hot.
