In my book tartare sauce, tomato sauce (ketchup) and lots of fresh lemon wedges are non-negotiables, but you can bulk out the meal with fresh salads - I like something crunchy and fresh like an Asian slaw, shaved zucchini salad or smacked cucumber salad. Soft garlic butter dinner rolls or no-knead focaccia are also great options, served with roasted garlic butter or wild garlic butter on the side.
