Boil a kettle. Place the spinach in a colander and pour the freshly boiled water from the kettle over it. Once the spinach is cool enough to handle, give it a good squeeze and chop it into small pieces. Halve the cherry tomatoes. 

Add the chicken mince, garlic powder, soy sauce, salt, pepper and spinach to a large mixing bowl. With clean hands, knead until all the ingredients are fully combined. Divide the mixture into 10/15/20 pieces and shape each piece into a meatball. Refrigerate. 

Bring a large pot of salted water to the boil. Once boiling, add the pasta and cook for 8-10 min until 'al dente' or cooked to your liking. Drain and reserve a cup of pasta water

Meanwhile, heat a pan over a medium-high heat with a generous drizzle of olive oil. Add the meatballs and tomatoes and fry until the meatballs are browned and the tomatoes start to pop. 

Once the meatballs are browned, add the measured water (use the reserved pasta cooking water!) to the pan with the stock cube, olives, half the Grana padano and the cream cheese. Simmer for 3 min or until the meatballs are cooked through but not too dry. Season with salt and pepper. Rip the fresh basil leaves into the sauce.

Toss the drained spaghetti in the sauce. Divide among plates and sprinkle with the remaining Grana padano.
