Soak the beans with water. In the morning, we cut the onion into the pressure cooker until it turns pink.
Then add the tomato paste and roast until it smells.
Then we filter the water of the beans in the pan and add to the pot.
We add sausages on it (how much you want to add) then add oil, salt and sugar and add water and close the lid.
After boiling (after blowing the whistle) we cook for 30 minutes on low heat.
ENJOY YOUR MEAL!
