Cheesy Grilled Bread

Preheat an outdoor grill for medium heat and lightly oil the grate.

Combine butter, tomatoes, pesto, garlic, salt, and black pepper in a food processor. Pulse until thoroughly combined and tomatoes are chopped. Scrape into a bowl and stir in 1 cup shredded provolone cheese.

Grill bread on the preheated grill until toasted, about 1 1/2 minutes. Spread butter mixture equally onto cut sides of both halves of bread and sprinkle with remaining cheese. Grill bread, cut-side up, over indirect heat with grill covered, until toping melts, 8 to 10 minutes. Let cool slightly; cut into slices using a serrated knife. Serve warm.
