Sooo, I made this today. I didn't have spinach (Ran out late last night ) but it turned out absolutely heavenly. I omitted miso paste and olive oil and used 2% milk, also. I'm a little cheap so those small things I don't invest in. This was heavenly. I think in the end it was only about 222 calories for one huge serving because I used whole wheat pasta. Heck yes. Picture of mine at the bottom of the post!

Want to enjoy creamy pasta without having to f***ing worry about cholesterol? Puréed cauliflower makes this sauce silky without any of that added bulls*** that made you avoid creamy sauces for so long. Feel free to add some stuff like roasted asparagus, steamed broccoli or roasted red peppers to this dish to mix it up.

• 1 pound pasta (fettuccine, linguine, spaghetti, whatever)
• 4 cups chopped spinach
• Salt and pepper
• 1/2 head cauliflower (about 1 pound), cut into little trees
• 1/2 cup unsweetened plain nondairy milk
• 2 or 3 cloves garlic, minced
• 1 tablespoon lemon juice
• 1 tablespoon olive oil
• 1 teaspoon miso paste
• 1/3 cup minced fresh parsley

Cook the pasta according to the package directions or whatever f***ing method you invented and now swear by. When it’s all done, throw it in a large bowl with the spinach, toss, and set aside. While the pasta cooks, bring a medium pot of water to a boil. Throw in a pinch of salt and the cauliflower and simmer all that until the cauliflower is tender, 5 to 7 minutes. Drain the cauliflower and toss into a blender. Add the milk, garlic, lemon juice, olive oil, miso and 1/8 teaspoon salt to the blender and let that motherf***er run until the sauce is creamy. Taste and adjust as you see fit. Pour the cauliflower purée into the pot you boiled the cauliflower in and set over low heat. Add the pasta and spinach and toss until everything is mixed and warm. Top with some parsley, salt and pepper to taste. Serve hot.
