  2. MAKE THE CREAMY SAUCE: Meanwhile, melt vegan butter OR avocado oil over medium heat then sprinkle in flour and cook for 1 minute while whisking constantly. Slowly pour in broth, then milk, coconut cream & cream cheese while whisking to prevent lumps from forming. Continue cooking and stirring until sauce reduces and thickens - taste and season with salt, pepper, onion salt & garlic powder as needed. 

    POUR the thickened sauce over the roasted broccoli and cauliflower.
