For this easy meal, delicate angel hair pasta is tossed with an umami-rich sauce of sun-dried tomatoes, garlic, mint, white wine vinegar, and tomato paste. The whole shebang is topped with crunchy toasted pine nuts.
In a food processor, blitz the sun-dried tomatoes, mint, oil, vinegar, tomato paste, garlic, salt, pepper flakes, and sugar until smooth, 1 to 3 minutes, scraping down sides of the bowl as needed. Transfer to a large heatproof bowl.
Bring 4 quarts of water to boil in a large pot. Add the pasta and 1 tablespoon of salt and cook, stirring occasionally, until al dente. Reserve 1 1/2 cups pasta cooking water, then drain the pasta in a colander. While the pasta drains, whisk 1 cup of the reserved pasta cooking water into the sauce.
Add the pasta to the sauce and toss gently with tongs, adjusting consistency with remaining reserved pasta cooking water as needed. Sprinkle with pine nuts. Serve with the grated Pecorino.
