Preparation

• Bring a large pot of well-salted water to a boil.
• Meanwhile, heat 2 Tbs. of the oil in a 12-inch skillet over medium-low heat. Add the garlic and cook, stirring, until fragrant, about 30 seconds. Add the spinach, increase the heat to medium high, and cook, stirring, until the spinach begins to wilt, about 3 minutes. Add the beans and 1/4 cup of the chicken broth. Cook, stirring occasionally, until the broth is reduced by half, about 2 minutes. Add the remaining 1/2 cup broth, the pepper flakes, and 1 tsp. salt; bring to a simmer. Turn the heat to low and keep warm.
• Boil the pasta according to package directions until al dente. Reserve 1/2 cup of the pasta water, then drain the pasta. Return the pasta to the pot and toss with the spinach-bean mixture, the remaining 1 Tbs. oil, and the lemon juice. Add a little of the pasta water to moisten, if necessary. Season to taste with salt and lemon juice. Serve drizzled with more oil and topped with grated cheese.

The spinach, beans, and cheese also make a great topping for bruschetta.
