Dianne Wenz, who I am honored to call friend, wears many hats, and all of them fit to perfection.  She is a health coach, a mentor to IIN students and runs two blogs, Chic Vegan and Dianne’s Vegan Kitchen. I had the pleasure of working with Dianne when she was enrolled in Essential Vegan Desserts at Rouxbe (read what she had to say here). Now Dianne can add cookbook author to her resume with her just launched, fabulous book, Truly Healthy Vegan Cookbook. (She has another on the way, too.)  I am thrilled that Dianne, as busy as she is, has agreed to do a guest blog post and a cookbook giveaway today.

Here are some great tips from Dianne, straight from the cookbook, just in time for the New Year and Veganuary.

Meal Prepping Tips

I find that life is much easier when I plan and prep. Here are a few ways I like to save time, and a little money, in the kitchen:

  1. Buy in bulk. A lot of grocery stores have bulk bins full of nuts, seeds, grains, and dry beans. They’re always cheaper than their packaged counterparts. Plus, because there’s no packaging, it saves pantry space and helps the environment by not contributing to landfills.
  2. Chop veggies ASAP. I chop my vegetables as soon as I get home from shopping and store them in containers in the fridge until I’m ready to cook. Heartier chopped vegetables, like cauliflower and broccoli, can last for up to a week. More delicate vegetables, such as leafy greens and bell peppers, will only last a day or two.
  3. Cook ahead of time. Grains and dry beans don’t take much effort to cook, but they take a little bit longer than vegetables. I like to cook up a batch of grains or beans at the beginning of the week and store them in containers in the fridge or freezer, so they’re ready to go when I’m ready to make dinner.
  4. Mise en place. This is French for “everything in its place.” It may sound fancy, but, simply put, it means prepping all of your ingredients, including chopping veggies and measuring spices, ahead of time. When it’s time to cook, everything is ready to go. Et voilà—dinner is ready!

Some meals, like this Spinach Mushroom Frittata, can be prepared in advance. Cook the mushrooms and make the tofu mixture ahead of time and place them in the fridge overnight. In the morning, just pop it into a pan and bake it. Breakfast is served!

Spinach and Mushroom Frittata

Dianne Wenz
Brunch is my favorite meal, and I take it very seriously. I usually make a big brunch on Sundays, with fresh fruit, whole grain toast, and a frittata, like this one. I love the flavor combination of spinach and mushrooms, but if it isn’t your thing, you can use pretty much any type of vegetable and leafy green. Red pepper and arugula would be great, as would zucchini and baby kale.
Prep Time 10 minutes
Cook Time 50 minutes
Servings 4


  • 1 teaspoon neutral-flavored oil such as grapeseed or avocado, vegetable stock, or water
  • 8 ounces cremini or white button mushrooms coarsely chopped
  • 2 garlic cloves minced
  • 1 14-ounce block of extra firm tofu, drained and pressed
  • 3 tablespoons nutritional yeast
  • 3 tablespoons plain unsweetened nondairy milk, such as soy or almond
  • 2 tablespoons lemon juice
  • 1 tablespoon cornstarch or arrowroot
  • ½ teaspoon dried basil
  • ½ teaspoon dried thyme
  • ½ teaspoon turmeric
  • ½ teaspoon sea salt
  • ¼ teaspoon black pepper
  • 5 ounces baby spinach


  • Preheat your oven to 375°F and lightly oil an 8-inch pie pan.
  • Heat the oil in a large sauté pan or cast iron pan over medium-high heat. Add the mushrooms and garlic, and cook, stirring occasionally, until they begin to brown. Remove the pan from the heat.
  • Place the tofu, nutritional yeast, nondairy milk, lemon juice, cornstarch, dried basil, dried thyme, turmeric, sea salt, and black pepper into a food processor and process until smooth.
  • Add the spinach and mushroom mixture to the food processor and pulse two or three times to incorporate. [If you don’t have a food processor, coarsely chop the spinach. Mash the tofu mixture together with a potato masher or large fork until all of the large lumps are gone. Fold the mushrooms and spinach into the mixture.]
  • Pour the tofu mixture into the prepared pie pan and smooth it with a spatula or wooden spoon. Bake for 40 to 45 minutes, or until the frittata is golden brown. Let the frittata sit for 10 to 15 minutes to firm up a little before slicing.
