Nutrition Information is approximate.Freezing & Storing in the Fridge: I find that freezing this sauce works well. Freeze as airtight as possible to avoid freezer burn. I like thawing this for use in baked recipes, I often make a double batch so I have some left to freeze.Make-Ahead: This is a great make-ahead item. Especially because it tastes even better after it has time to sit overnight and let the flavors mingle. It a nice sauce to keep in the fridge and enjoy throughout the week.Vegan Parmesan: The main ingredient substitution is parmesan cheese. This Easy No Harm Parm is milder in flavor and finer in texture than my Garlic Shake and works well in this recipe.For a Meaty Sauce: I usually make this as a basic, meatless sauce. If you want to make a ground beef style sauce, you can add Boca Original Veggie Crumbles or Gardein Beefless Ground to your sauce.www.planttestkitchen.com
