Trim the stems off the Portobellos. Wipe clean with a damp paper towel. Using a small knife or a skewer, make a series of holes in the gill-side of the mushroom caps, about 1/2 an inch apart. Insert garlic slivers in some of the holes, Romano cheese slivers in some, basil in some, and pine nuts in the remaining holes.


Spread some of the pesto sauce on the bottom of a platter or baking dish. Arrange the mushroom caps on it, and swish them around to coat the bottoms evenly.

Spread some of the pesto sauce on the bottom of a platter or baking dish. Arrange the mushroom caps on it, and swish them around to coat the bottoms evenly. Spoon the remaining marinade over the Portobellos. Let them marinate, covered, for as little as 30 minutes or as long as 3 hours.

Set up the grill for direct grilling, keeping one zone cool, and preheat to high.

Set up the grill for direct grilling, keeping one zone cool, and preheat to high. When ready to cook, remove the mushroom caps from the marinade and wipe off any excess. Arrange the mushroom caps on the hot grate, gill-side down, and grill for 3 minutes.

Then turn the caps over and continue grilling until the caps are browned and very tender, 4 to 6 minutes, rotating after 2 minutes to create grill marks.

Divide the Taleggio cheese among the caps (the gill-side should be up) and move to the cooler side of the grill until the cheese melts.
