That's smoked, pulled meat (veal) with marinated, grilled portabellas and oven-roasted tomatoes.
I cut the mushrooms horizontally and marinated them in commercial dressing for over an hour on the counter.
Could have made my own, but why not use what is to hand?
I set the grill to "high" and it took almost an hour to cook these the way I wanted. Turning, turning, waiting for them to exude all their excess moisture and concentrate their flavor.
You can almost see the umami.
Finally, they were flat, a little shrunken, and nicely browned.
In the meantime, a bunch of tomatoes were coated in sunflower oil, salt, and placed in a 400f oven for about an hour.
Ready for a sandwich. The excess was frozen for sauces, later.
Great flavor and texture combination. Sweet BBQ sauce on the meat, mustard on the buns. Sweet/sour, more sour with the marinated mushroom and more sweet with the roasted tomato.
Layers of perfection! It was a bit of a time commitment to make, but for someone who doesn't have sandwiches that often - well - I had put a lot of thought into how it was going to go down, and was completely satisfied with the result.
