Chop the spring onions, the anchovies & the dried tomatoes.
Dice the mozzarella.
Mix tomato pulp, tomato purée & dried herbs.
Start frying the spring onions, dried tomatoes, anchovies in olive oil for about 4-5 min.
Add tomato mix, warm/hot water & spaghetti.
Bring the mess to a boil & let it simmer (altogether about 12-15 min).
Stir continuously to keep the spaghetti from sticking.
Add a pinch of sugar to taste.
Add salt & pepper as well.
Finally add the diced mozzarella, stir once again & let it simmer - only for 1-2 min.
Serve at once.
