How to Make It
Cook the penne in boiling salted water until al dente. Drain the pasta, reserving 1/2 cup of the pasta water.
Meanwhile, in a large skillet, heat the olive oil until shimmering. Add the garlic and cook over moderately high heat until golden, about 2 minutes. Add the drained tuna; cook for 1 minute. Add the wine, capers and 1 tablespoon of the parsley; season with salt and pepper. Cook the sauce until the wine has nearly evaporated, about 2 minutes longer. Add the penne and the reserved pasta water and cook, stirring, for 1 minute. Season with pepper, sprinkle with the remaining 1 tablespoon of parsley and serve.
