Dice ½-1 yellow onion, depending on how large it is, set aside.
Cut the ends off of 2 garlic cloves and smash them, set aside.
Pour out half of the cannellini beans and set aside.
The other half of the beans, puree.
In a pot, add pancetta and a little olive oil and sautee.
Once it has a little color, but not burning, add the onions and garlic. Sautee till translucent.
Add tomato paste and tomato bouillon to the pot. Let cook for about 1-2 minutes.
Add the chopped tomatoes and italian seasoning to the pot. Let cook for about 4-5 minutes.
Add in the whole beans, the pureed beans, and the water. Stir till combined. This has to cook for about 15-20 minutes.
In the meantime, set a separate pot to boil and cook your ditalini till al dente.
Drain the ditalini directly into the soup pot. This isn't a very liquidy soup, it is more hearty and thick. Remove from the heat
Top with pecorino romano cheese and parsey, serve immediately as it will thicken and dry up when left.
