A quick weeknight pasta that pairs whole wheat noodles with white beans and greens for a fiber-dense plate.
Cook the pasta in salted water until al dente, reserving 1/2 cup of the water before draining.
Warm the oil and garlic in a large pan until fragrant, then add the chili flakes.
Add the beans and greens and cook until the greens wilt, about 4 minutes.
Toss in the pasta and reserved water and stir until glossy.
Season, top with parmesan if using, and serve.
