How to Make Marinated Cauliflower Salad Recipe
Step 1: Prepare the Dressing
Begin by creating a beautifully balanced dressing that will soak into the cauliflower and veggies. In a jar or bowl, combine the olive oil, red wine vinegar, Dijon mustard, garlic powder, Italian seasoning, salt, pepper, and grated Parmesan.
