Bring a large pan of salted water to the boil. Add the pasta and cook according to packet instructions until al dente (8–10 minutes). Just before draining, reserve a cup of the pasta water. Drain and return pasta to the pan.
In a blender, add the drained white beans, The Happy Pear Sundried Tomato Pesto, garlic, lemon juice, and 3 tablespoons of reserved pasta water. Blend until smooth and creamy. Add an extra tablespoon of pasta water if needed to loosen the sauce.
Taste and add salt and pepper to your liking.
Pour the sauce over the cooked pasta and stir well to coat evenly. Heat gently if needed.
Serve as is or top with sautéed spinach, fresh basil, toasted pine nuts, or a sprinkle of nutritional yeast for a cheesy finish.
