Mashed Cauliflower and Arugula Stuffed Portobellos #WeekdaySupper #ChooseDreams

This post is sponsored by American Family Insurance. The recipe and opinions are my own.

In an attempt to eat healthier, my family and I began incorporating a weekly “Meatless Monday” and a plant-based diet into our dinner menu. At first, my family fought the new, healthy change, especially since a meatless menu would force them to eat more greens. Once my husband and three children realized that meatless dishes would include hearty vegetable alternatives like portobello mushrooms, they were on board.

Then, I took our healthy Meatless Monday meals one step further by trying incorporate carb-free alternatives, such as mashed cauliflower. By steaming and “mashing” cauliflower with bit of parmesan cheese, it helps mask the vegetable which often turns kids’ (and husbands’) noses. Of course, before they even tasted, my family fought me, but once they tried it, they loved it.

By substituting cauliflower for is starchy counterpart, I cleverly fed a vegetable that is rich in fiber, potassium, vitamin K and vitamin C.  Plopping some cauliflower on top of a portobello mushroom, I offered my family a double dose of potassium in one Meatless Monday #WeekdaySupper.

And then, I threw some steamed arugula at them.  Oh the horror of eating heart healthy veggies! 


Once my family could overlook the added green, they learned to love the richness, flavor and color the arugula added to this white earthy, healthy meal.

With adding arugula to this already healthy dish, it delivers even more vitamin A, K and C as well a calcium and iron.  Plus, in the heat of the summer, arugula also helps hydrate your body. This one gluten-free, Meatless Monday #WeekdaySupper delivers a stack of superfoods that packs a healthy punch, which is so important for growing children and a long distance runner like me.  One portobello cap (or two because their carb-free and so healthy) fuels me to run multiple miles and continue to #ChooseDreams of running more marathons.

  • 1 head of cauliflower
  • ¼ cup parmesan cheese, grated

    Your kids sound like mine! The entire time I’m planning and cooking anything healthy they’re saying how gross it is until they ask for more. This looks really good, we’ll have to try it next weekend. I’ll make my daughter clean the mushrooms, she’ll love it. 🙂

    Your entire menu looks great this week. I’m certainly going to try the Mashed Cauliflower and Portobello Mushrooms since they are both big hits individually in our house. Yum!
