Tuna and spinach pasta in tomato sauce

Slice the onion thinly

Heat ingredients A in a frying pan, and once fragrant, add the onion and sauté. Add ingredients B and sauté briefly, then add the white wine to enhance the flavor

Quickly blanch the spinach, squeeze out the excess water, chop it roughly, and add it to the pan from step 2 along with the tomato sauce

Cook the spaghetti until al dente. (One minute before the time indicated on the package. In this case, about 2 minutes and 30 seconds.)

Add the cooked spaghetti to the frying pan, drizzle with olive oil and freshly ground black pepper, then transfer to a plate, sprinkle with parsley, and it's done
