Soup with vegetables

Here a simple recipe to prepare a tasty soup with vegetables. Before starting make sure you have the following ingredients: 2 potatoes without peel, 3 carrots, 10 green beans with the ends cut, 1 pepper, 300ml tomato sauce, salt, oil of olive, 1 onion without peel.
So, let's start!

• Cut the potatoes, carrots, green beans, pepper, onion in small pieces, not so small though.
• Put these ingredients in a pot and fill it with the water.
• Light the fire and wait till the water in the pot start to boil.
• Once it's boiling reduce the level of firing to minimum and let it boil for other 60 minutes; really this is important, the level of firing should be very low, you should observe the level of water just boiling a bit.
• Add the potatoes in the pot.
• Add two spoons of oil of olive and a bit of salt.
• Let it boil, always with low fire, for about 25 minutes.
• Add the tomato sauce and half of dado knorr
• Let it boil for the last 5 minutes.

Finally serve it hot in a dish with some slices of bread.
I learned how to prepare it today in the soup session with my friend Cristian, I hope to have not forgotten some steps so I won't consider myself responsible of the success of the soup ;-)
