Kidney Bean with Oilve Oil

1 day in advance, put the red mullet in salty cold water, we cover the mouth. The next day our kidney beans will be swollen.
We filter and wash the water and take it to our pot, put enough water over it and let it boil. Approximately 20-25 minutes later kidney beans will be softened slightly. We're draining the water and taking it aside.
We take the oil, chopped onions and carrots in the pot and start roasting.
We continue to take crushed or grated garlic, potatoes and tomato paste respectively.
Then we add the kidney beans we've drained and throw the sugar.
We add 1.5 liter of water and salt to the end, cook the food thoroughly and cook until the kidney beans soften (with the addition of more water if necessary).
We keep the cooked food in the saucepan without opening the lid until it reaches room temperature.
After coming to room temperature, we put it in the fridge and serve it when it cools

Enjoy your meal.
