Cooking Mode

1. Preheat the oven to 180ºC.
2. Start by peeling the potatoes and cutting them into cubes. Place them in a pot with salted water and cook until tender. Drain the water and mash the potatoes with a fork.
3. In a skillet, heat the olive oil and add the chopped onion. Sauté until golden, then add the garlic, soy sauce, balsamic vinegar, and all the seasonings. Cook over low heat for another 3 to 5 minutes. Add the beans, then turn off the heat.
4. Fold the mixture into the mashed potatoes. Add the tomato sauce, oats, and chopped walnuts. Mix everything together with your hands.
5. Line a loaf pan with parchment paper and transfer the mixture to it.
6. Press down firmly. Bake for about 40–50 minutes.
7. When the roll is done, let it sit for 15 minutes in the turned-off oven.
8. Remove from the oven and let cool. Refrigerate for about three hours for a firmer texture.
