Roasted Portobello Mushroom Packets with Garlic, Shallots, and Balsamic Vinegar
I love mushrooms! They add that indescribable umami flavor to everything and Portobello ones add meaty heft as well. Here's a variation of the roasted mushroom packets.

Instructions
Preheat the oven to 400°F and coarsely chop the shallots and trim the ends of the garlic. Throw the shallots in a food processor to finely mince (or mince by hand).
Add your choice of fat and vinegar to the minced alliums in a 3:1 ratio of fat to vinegar. Season the vinaigrette mixture with a good sprinkling of salt and freshly ground black pepper.
Place each Portobello mushroom on a piece of heavy-duty aluminum foil, stem side up. Lightly coat each ‘shroom with extra virgin olive oil and some salt and pepper. Put a dollop of vinaigrette into each mushroom, spreading until the cap is filled.
Tightly seal each mushroom packet and place on a baking tray. Stick the tray in the oven and roast for ~25 minutes.
Remove the mushroom from the packets (watch out for the steam!) and slice up.
