Ingredients

3 ears corn

1 English cucumber

1 small red onion

1 cup grape tomatoes, halved

1 bunch watercress

3 tablespoons red-wine vinegar

2 tablespoons olive oil

Coarse salt and ground pepper

Preparation

Cook corn in a pot of boiling salted water until crisp-tender, 8 to 12 minutes. Run under cold water to cool completely. Slice off kernels with a sharp knife.

Peel strips from cucumber, quarter lengthwise, and thinly slice crosswise. Combine in a large bowl with tomatoes, watercress, trimmed and torn into bite-size pieces, and cooked corn kernels.

Just before serving, drizzle with vinegar and olive oil, season with coarse salt and ground pepper, and toss.
