Roughly cut 40 g spinach and 100 g mushroom of your choice. Cut 40 g bacon into cubes.
Bring a pot of 1600 ml water to a rolling boil and add 160 g dry spaghetti to a pan of boiling water along with 1 ½ tsp salt. Cook according to the instructions on the packaging.
Heat a frying pan on medium and add 1 tsp cooking oil and 2 tsp unsalted butter. Once the butter has melted, add the bacon and mushrooms.
Once the bacon is slightly crispy and the mushrooms are soft, add the spinach and 1 pinch salt and pepper.
Once the spaghetti is cooked, drain the water and transfer it to the frying pan. Add 1 tbsp soy sauce and mix well.
