anything but soy sauce

Well well, is not like the image. You will say "wow we have an expert here", but not: I'm not even near from a chef or something like this. I have the basic skills: make spaghetti, maybe cook some rice if I have wi-fi near, and eggs. Of course, cooking hamburgers too, but this hamburgers everybody can buy in the supermarket.
But I have this secret that makes everything taste batter: soy sauce. Soy sauce in the spaghetti! Soy sauce in the rice! Soy sauce in the cazuela? Let's try it! Just kidding, but I hope my point is clear. When I cook, nothing have sense until the soy sauce came in.
I remember that time I invited a friend to lunch, cause there's no one at my house and I didn't want to be alone. Anyway, I say to her "I'll make spaghetti", and she came in. I put the plates in the table and she look worried: "I told you that I'm not a big fan of the soy sauce". And I was like "oh oh oh", the spaghetti was brown in the soy.
After all, she love the mix and her opinions changed: now she makes the spaghetti with soy sauce too.
