I recommend the aglio olio sauce sold at Costco. This is very delicious. It costs 9,990 won for 10 pieces, so the price is similar to ramen. In the past, when I was sleeping alone, I often ate ramen when it was too lazy to eat, so if I just add some frozen shrimp and Cheongyang peppers, I can go to a restaurant.
There is someone writing spaghetti below so I'm posting it. After reading your post, I suddenly got a craving for spaghetti, so I'm going to make some aglio olio for tomorrow too. I always keep this sauce in the cupboard.
