Easy Grilled Portobello Mushroom Burger can be a vegetarian option for summer grilling. You can also bake this in the oven when grilling is not an option. This can be a vegetarian burger by leaving out the bacon. I had a few leftovers on this day, so I added them, though this is optional.
Tips: Increase the number of portobello mushrooms to serve your guests. The topping you use will also need to be increased. This is really easy and it’s a delicious vegetarian option.
