Orientle Spinach Salad

The make-ahead dressing transforms this simple salad.

Blend oil, vinegar, onions, sugar, salt, and ketchup together the night before serving.

Those flavors marry overnight into a balanced sweet-and-sour coating that clings to every leaf.

Crunchy water chestnuts and bean sprouts add Asian-inspired texture while bacon and hard-boiled eggs make it satisfying enough for lunch.
