- 8 red bell peppers
- 2 garlic cloves, very thinly sliced
- 1/4 cup olive oil
- 2 tablespoons (or more) sherry vinegar or red wine vinegar
- 2 tablespoons chopped marjoram, divided
- Kosher salt
- Heat broiler. Place bell peppers on a rimmed baking sheet. Broil, turning occasionally, until skins are blackened and blistered all over, 14–17 minutes. Transfer peppers to a large bowl, cover with plastic wrap, and sweat 15 minutes.
- Remove skins and seeds from peppers; discard. Tear peppers into about 2″-wide strips. Toss in a clean large bowl with garlic, oil, vinegar, and 1 Tbsp. marjoram; season with salt. Let sit at least 20 minutes and up to 4 hours.
- Just before serving, taste peppers and season with more vinegar and/or salt if needed. Scatter remaining 1 Tbsp. marjoram over top.
