Grilled Vegan Portobello Burger with Black Bean-Beet Patty

I have seen so many gorgeous vegan Portobello burger pictures all over social media, but only now did I decide to try creating one myself. Believe it or not, but it was easier than I initially thought. After all, I already had black bean-beet patty recipe that I knew would be perfect with the burger. So, it was just the matter of roasting the Portobello mushrooms and coming up with a tasty sauce for my vegan burger.

Now, for a burger, I prefer a sauce that’s not too runny. Otherwise it’d be uncomfortable to eat. As a result, I found thick hummus to be a wise choice. Since I wanted my vegan Portobello burger to be as colourful as possible and I already had brown as well as red represented, I went for yellow chickpea hummus with turmeric and cumin.

However, don’t stop there as you can use any hummus you like, e.g. Chickpea Hummus with Potatoes and Bell Pepper, Black Bean-Veggie Hummus, Beet-Red Bean Hummus.

Needless to say, the same goes for patties. For example, you could try Chickpea-Quinoa Patties or Chickpea-Summer Squash Patties.

Since I am still following Candida diet, I made my vegan Portobello Burger Candida diet friendly. Furthermore, my burger is also whole food plant-based, gluten-free, sugar-free and oil-free.
