I must admit - I might be biased on this one. I *love* portobello burgers. Or rather, I just love mushrooms of all kinds. But even for the more discerning mushroom eaters out there, I think these are worth trying. It's not because it's a meat substitute... it's just because it's good. This is a delicious meal all by itself without the need for comparing it to other things or sticking it in a group.
The trick here, of course, is marinating the mushrooms. Give them time to soak up the delicious flavors of balsamic vinegar, rosemary, and more, before grilling them. Don't worry, while the marinading takes a few minutes to sit, the rest comes together quite quickly. I then served my mushrooms with cheese, tomato, and aioli, all of which are in the menu below, but you should feel free to embellish however you like. Grilled (or not) red onion, leafy greens of some sort, and avocado would all be great additions as well!
