This peppy relish from Martha Stewart adds flavor to the likes of grilled salmon, chicken and even flatbreads.
1 Walla Walla sweet onion, finely diced
4-6 scallions, trimmed of root and tough green ends and finely diced
1 tablespoon white wine vinegar
1½ teaspoons sugar
Sea salt and pepper
1-2 tablespoons minced fresh herbs, such as parsley, mint, or cilantro
1. Place onion and scallions in a bowl of ice water; soak 20 minutes.
2. Drain the onion and scallions, squeezing in paper towels to remove as much liquid as possible; transfer to a bowl. Add sugar, vinegar, herbs, and a pinch each of salt and pepper to taste. Relish can be made ahead and refrigerated until ready to use.
