Dried parsley would probably be fine. Chives might also work.I'm thinking of doing this recipe this weekend. I have all the ingredients except the parsley. Never been a fresh parsley guy.
Danny what do you think the sour cream is for flavor and moisture? Do you think shredded cheese could do a similar job? I might have some nacho cheese around still. I'm asking about cheese because I'm thinking of also trying a southwestern variant with onions, peppers, and a southwest seasoning.
Sour cream is probably mostly for moisture & flavor, as you guessed. If you sub a shredded cheese, you’ll have to watch your cooking time more closely- it might cook faster than the 5min she stated in the video because it won’t be as moist. You might be able to counter that with a little cream or milk.
And the tanginess of sour cream could be mimicked by using a little mustard powder or- again, adding moisture- a dollop of mustard.
Greek yogurt might also work as a moist and tangy ingredient.
