- 4 medium red beets , trimmed
- 1/2 cup red wine vinegar
- 1 1/2 teaspoons salt
- 2 medium red onions , each sliced into 1/2-inch-thick slices
- 2 tablespoons extra-virgin olive oil

Meanwhile, heat a grill or a grill pan. Brush both sides of onion slices with olive oil; sprinkle with pepper and remaining 1/2 teaspoon salt. Grill onions over medium heat until evenly charred and tender, 2 to 3 minutes per side.
In a small bowl, whisk together vinegar, brine, honey, oregano, salt, and pepper. Gradually add oil, whisking in a thin, steady stream until blended.
