Interesting sole recipes, a good rub or marinade?

I agree with @June about not marinating sole. It has such a mild flavor that any marinate would overpower it. My suggestion would be to lightly salt it, bake or pan fry, and then top with toasted lemon-herb breadcrumbs.

I wouldn't marinate sole. It's a very fragile fish and likely to fall apart. Besides, if you marinate any fish you won't taste it, you will taste the marinade. I like to pan fry sole in butter, take it out when done and proceed to turn the butter into browned butter (you have to use unsalted butter for this) and finish with some toasted, slivered almonds.

Pan fry your sole in butter. Make sauce vierge! Gently heat olive oil with cherry tomatoes, basil, cilantro, parsley, and chives. Add tons of lemon juice. Salt and pepper to taste.
