There are about a gazillion ways to cook pasta using other pantry staples — things like garlic, bread crumbs, pecorino, capers, olives and especially, canned fish. This recipe, pasta with tuna, anchovies and capers, showered with lots of green herbs and scallions, is one of my family’s household favorites. I like it with a long, thin, twirlable pasta — spaghetti, linguine or bucatini — but you can use whatever pasta you have on hand. Even macaroni works just fine and might even persuade your finicky kid to eat this dish (though, so far, mine abstains).
