    This vegan grilled portobello recipe features sweet roasted pumpkin and caramelized walnuts, for a simple yet delicious dinner meal.

    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 Mushroom with roasted Pumpkin mash and caramelized Walnuts.

    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.

    The roasted pumpkin purée is the perfect combo for grilled portobello's. It gives a smoked sweetness taste, and goes hand-in-hand with some crunchy caramelized walnuts.

    It's officially pumpkin season, and pumpkin mash is definitely one of the most delicious things you can make ( together with these incredible pumpkin recipes).

    You can also add two slices of bread or a toasted brioche bun to turn your portobello into the tastiest vegan burger you could possibly make.

    Whether you serve it with bread or not this grilled portobello mushroom is sure to satisfy even the most convinced carnivores!
