¼ small loaf country-style bread (about 6 oz.), crust removed, bread torn into large pieces
6 tablespoons olive oil, divided
Kosher salt and freshly ground black pepper
2 large red bell peppers, halved, ribs and seeds removed
2 small red onions, peeled, quartered, with some root attached
3 tablespoons red wine vinegar
½ teaspoon paprika, preferably smoked
2 tablespoons coarsely chopped fresh chives, or scallions, plus more for serving
Prepare grill for medium-high heat. Toss bread with 2 tablespoons oil in a medium bowl; season with salt and pepper. Toss bell peppers and onions with 2 tablespoons oil; season with salt and pepper.
Grill bread, turning occasionally, until golden brown, 8–10 minutes. Transfer to a plate.
Grill vegetables, turning often, until very tender and charred in spots, 8–10 minutes for peppers and 10–12 minutes for onions; transfer to a cutting board.
Trim root end from onions and separate layers. Transfer to a large bowl, add vinegar and paprika, and toss to coat. Remove as much skin as possible from peppers; discard. Cut into 1½” strips.
Add peppers, grilled bread, 2 tablespoons chives, and remaining 2 tablespoons oil to bowl with onions and toss to combine; season with salt, pepper, and more vinegar, if desired. Serve topped with more chives.
