This is a super simple vegetarian mushroom cheeseburger that I adore, so thought I would share it.
To make this, I wiped my griddle pain with olive oil and put it on the heat. I then put the large portobello mushrooms on the pan to start cooking. I sliced open the bread rolls and then placed them on the griddle also to toast them. The key to this burger is toasting the bread as it gives another texture. Without doing so, it can be a bit too soft and mushy for me.
Once the mushroom was cooked and the bread toasted, I put them together, topped the mushroom with some feta cheese and chilli flakes =)
