I am planning a menu for a special night with friends. I am a little torn (and stumped) about what to put with the Swedish Meatballs in a creamy lingonberry gravy and Yukon gold potato patties. I was thinking braised fennel, but the color is so similar to the other dishes, I'm afraid it would be unappetizing. I had thought of Brussels sprouts, but not everyone loves them. I think the menu needs something a little tangy or vinegary to offset the richness of the meatballs and potatoes.
Also, what would you start the meal with?
