Make this portobello burger

Until recently, mushrooms were my least favorite food in the world. Portobello mushrooms, however, were my gateway into a world of intense mushroom appreciation. If you’ve never tried a grilled portobello burger, you’ll be surprised at how juicy and flavorful it can be. Mushroom haters, try it! They’re the perfect medium for a smoky and grilled flavor!

This summer we created a new version of the Portobello burger with Greek or Mediterranean toppings. It is placed on focaccia bread with dill and Greek cucumber tzatziki sauce. We used mint and dill from our garden and then decorated with some feta cheese and red onions. It turned out incredibly delicious and has been one of our favorite sandwiches ever since. Served with a salad of crunchy romaine lettuce, juicy tomatoes and Greek dressing – or a Greek salad itself!

How to Grill Portobello Mushrooms

Portobello mushrooms are very easy to grill. For our Portobello burger, we marinate the mushrooms with balsamic vinegar and olive oil before grilling. Let them sit for about 15 minutes while the grill preheats. When the grill is ready, place the mushrooms on the grill and fry on each side until juicy, about 5 minutes. That’s it! The mushrooms will release some liquid and become charred and delicious.
