How to Make It
Light a grill. In a small bowl, mix the vinegar with the honey, mustard, 1/4 cup of the olive oil and the reserved 1 tablespoon of red pepper oil. Season the vinaigrette with salt and pepper.
Brush the ciabatta slices on both sides with olive oil and grill over high heat until lightly charred, about 1 minute per side. Let cool slightly, then cut into 1-inch cubes.
In a large skillet, heat the remaining 1 tablespoon of olive oil. Add the garlic and shrimp, season with salt and pepper and cook over moderate heat until the shrimp are pink and curled, about 1 minute per side. Scrape the shrimp and garlic into a bowl and let cool slightly.
Add the roasted red peppers, onion, chives and croutons to the shrimp. Pour the vinaigrette over the salad and toss well. Transfer to plates and serve.
