This was very fast, easy and, with a few tweaks, very good. I mixed up everything but the spinach and pasta first, adding a couple extra tablespoons of olive oil, a tablespoon of lemon juice, and a generous sprinkle of red pepper flakes. Then, because I only had spaghetti to work with, I decided to mash the beans up a bit so they could stick to the pasta, which ended up working beautifully. Once the pasta was done, I mixed it, the spinach, and about 1/2 cup of pasta water in with everything else, then threw it back it the pot and on the stove for a couple of minutes until everything was heated and the spinach was wilted to my liking. I ended up with a really nice, thick sauce that coated the pasta very well and was quite tasty. I'll definitely make this again.
