This is what I had, I made it from Passover dinner leftovers and cheese

Romaine lettuce 

Horseradish Mustard (some think it's not kosher for Passover, I disagree, in fact I use it every Passover in my salad dressing recipe I make, I think it goes great with the theme of feasting on bitter herbs)

Cheese 

Onion 

 

 

It isn't amazing but it's kinda good and not so bad
