Start by wrapping a slice of bacon around a handful of spaghetti pasta.
Transfer everything to a large skillet over medium to low heat and fry until the bacon is golden brown.
After doing that, transfer to another large skillet, add the tomato paste, the water, the tomato sauce and stir to combine.
Season with a pinch of salt, a pinch of black pepper and cover the skillet.
Turn on the heat to medium-low and cook for 10 minutes.
After this time has passed, remove from the skillet and transfer to a medium baking dish.
Pour the remaining sauce from the skillet all over the pasta and spread it evenly.
Cover everything with the grated mozzarella cheese, take it to a preheated oven at 200° C (400° F) and bake for 15 minutes.
Serve.
