This is a super easy & tasty dish. I just made it (through step 4) & will serve it tomorrow. But I tasted a little with the watercress & it was great. I'm wondering if it would make a big difference if I add all of the watercress now? Hmm. I'm afraid it'll get was too soggy/limp, etc. if I add it now. But I am afraid if I don't add it, the watercress will not stay until tomorrow. I'll take my chances & just add it tomorrow.
