Growing up in Hawaii I was exposed to teriyaki flavored everything. From teriyaki chicken and beef teriyaki to teriyaki tuna and pineapple teriyaki pork kabobs. Teriyaki sauce is also a popular flavoring for vegetable dishes, which is why the notion of a Portobello Mushroom Sandwich coated with sweet teriyaki sauce is not completely foreign to me. However, I underestimated how incredible the combination of teriyaki sauce, portobello mushrooms and balsamic vinegar could be when I ordered this next dish at a local vegetarian restaurant last week.
Portobello mushrooms are considered the steak of the mushroom world and for good reason. While this sandwich doesn’t feature a hint of meat you never miss it. The mushrooms are hearty and bursting with flavor from the teriyaki sauce, balsamic vinegar and the sun dried tomato mayo (which I almost asked to be put on the side because I wasn’t sure if it would clash with the teriyaki sauce—-it didn’t).
If you have never had a portobello mushroom or experimented with teriyaki sauce (which is typically found in Asian dishes) this sandwich is a great place to start.
