Instructions

• Prepare the barbecue for direct and indirect cooking over medium heat (180° to 230°C). If using a Weber Q barbecue, set up your barbecue with a convection tray and a trivet.
• Lightly coat the cherry tomatoes with oil, then season with salt and pepper. In a food processor blitz together the bread, garlic, Parmesan, and 10 basil leaves until the mixture has turned into fine crumbs. Using a basting brush, brush the mushrooms all over with oil. Season with salt and pepper.
• Grill the cherry tomatoes over direct medium heat, with the lid closed, until they just start to blister, about 4 minutes, turning once halfway through cooking time. Remove from the barbecue.

• Assemble the mushrooms by placing the cherry tomatoes into the mushroom cavities. Tear the cheese into small chunks and add to the mushrooms. Top with the blitzed bread crumb mixture.
• Roast the portabella mushrooms over indirect medium heat, with the lid closed, for 15 to 20 minutes. If you are using a Weber Q, place the mushrooms on the trivet. Roast the mushrooms until the crumbs are golden and the mushrooms are cooked to your liking.
