Vegan Cauliflower Alfredo Sauce

Heat olive oil in a deep pan over medium heat. Cook and stir onion until soft, about 5 minutes. Add garlic and cook for 2 minutes more. Add cauliflower, vegetable stock, basil, and rosemary. Cover pan and cook until cauliflower is soft, 15 to 20 minutes.

Meanwhile, bring a large pot of lightly salted water to a boil; cook rotini at a boil until tender yet firm to the bite, about 8 minutes.

Pour cauliflower mixture and almond milk into a food processor. Puree until smooth. Season with salt and pepper. Drain pasta and ladle cauliflower sauce on top to serve.
