Keep a cooking pot with water and salt to boil and cook the gnocchi as per package instructions.
They are done cooking when the gnocchi swim to the surface. Take out from the water and keep aside. Tip: So that they don't stick together mix a few drops of olive oil into the gnocchi.
Pomodoro Sauce
Peel and chop garlic, peel, and dice onion.
Heat up a skillet with olive oil and saute onion soft. Keep it on a medium flame.
Stir garlic into onion and saute for another 1-2 minutes over a medium heat setting.
Reduce the heat to slow. Stir peeled whole tomatoes into the pan, as well as the tomato sauce. Mix it all in.
Season with salt, black pepper, and sugar and combine. Adjust sugar quantity to your needs. Add more or less sugar depending on how sour the tomatoes are.
Increase the heat setting back to medium and cook your sauce for about 10 minutes or so, stirring occasionally. The flavors will develop and when it tastes delicious that's when it's ready.
Turn heat off and stir fresh basil leaves into the sauce. Mix into the sauce.
To Serve
Mix gnocchi into a sauce or serve with sauce over gnocchi.
Garnish to your liking with parmesan, a drizzle of olive oil, and/or fresh basil leaves.

Notes
The addition of sugar is needed in this sauce because canned tomatoes contain citric acid and that's making the tomatoes sour so to counterbalance that we add sugar.
