Step 1: Base ... Add the oil to a saute pan and bring to medium high heat. Add the onion and garlic and saute until slightly tender; about 2-3 minutes.
Step 2: Roux ... Then, add the flour and whisk until the flour is incorporated with the oil. Cook just a minute on medium heat, but make sure it does not burn or get too brown.
Step 3: Sauce ... Add the broth and bring to a light boil to thicken the sauce. Then, reduce the heat to medium low and add the beans, lemon juice (start out with 4 tablespoons, you can add more if you want), capers, and lightly season with salt and pepper. You can re-season after you add the spinach and toss with the pasta. Cook just a minute to incorporate everything.
Step 4: Pasta ... As the sauce cooks, cook the pasta according to package directions in plenty of salted water.
Step 5: Finish ... Drain the pasta and add to the sauce. I also like to add a little of the pasta water as well, it makes a nice creamy sauce; but not necessary. Add the spinach and lemon zest, toss to combine and cook just a minute; then finish with the fresh basil.
Step 6: Serve ... As I said, a side dish is how I like to serve it; but it is a great vegetarian dish, or you can always add some sliced chicken to make it a bit heartier. ENJOY!
