It’s Meatless Monday, and it’s the perfect time for this juicy steak-like grilled portobello mushroom with roasted pumpkin mash and caramelized walnuts. But first, what is meatless monday exactly about?

It’s an international campaign founded in US, that encourages people to not eat meat on Mondays to improve their health. This healthy habit is not only popular in America, but also in UK, Australia, Belgium and many other countries. Did you know San Francisco was the first city to officially declare meat-free monday the Vegetarian day of the week?  You can learn more about this campaign here.

I am personally a strong supporter of this initiative, and I think going veggie at least 1-2 days a week is a wise choice for yourself and the environment. It’s not only a healthy choice, but it can also be fun to experiment new flavors and try new recipes.

Portobello Mushrooms are very meaty and tender and known for their versatility -Just one tiny bite, and you won’t miss the steak – at least for tonight. Plus, thanks to their rich flavor they make a great vegan and vegetarian alternative.
