Anything that's fit for human consumption counts as a salad if you chop it into little cubes and mix it together with olives and feta.
chocolate? marshmallows? ghost peppers? liquids? ice cream?
I'm suspicious that all of those would work mixed together, but I'm sure that individually, each of those five things could work as a component of a salad with well-chosen other ingredients.
in the defence of the chocolate marshmallow ghost pepper unknown liuäquids ice cream salad is tht no one said it had to be a good salad, just a salad
also liquids is not even that weird in a salad, rhough usually they are called dressing
I'm actually pretty sure that there has to be a way to make a salad that includes dark chocolate, black olives and feta, and whatever the other ingredients might look like, whoever figures that out would also know what wine would suit best with it.
