This dish is sacrilege. Pissaladière is a sort of pizza, with a nest of sweet, burnished onions overlaid with a harlequin pattern of crossed anchovies and olive studs, atop a focaccia-like dough. Sicilian-style slices are for sale on the street corners of Nice, and it tastes like Nice: salty like the sea, with a touch of sweetness.
This pasta starts with multigrain spaghetti, because I think the more substantial texture more accurately recalls the chewy pissaladière dough. It also echoes the earthiness of the Provençal flavors of thyme and bay. Then, I incorporate all the flavors of pissaladière: caramelized onions reduced down to a sweet, slithery mess. Eager fillets of anchovy. Niçoise olives. Olive oil. The resulting pasta is tenderly sweet and predominantly sea-salty.
