Total time: 255 min
Ingredients: ½ cup sugar; ½ cup salad oil; ½ cup cider vinegar; 1 teaspoon salt; 1 can cut green beans; 1 can wax beans; 1 can garbanzo beans; 1 can kidney beans; ½ cup yellow onion

The beans drink in their sweet-sharp dressing as this salad rests, which is why it is better made ahead. By picnic time the onion has mellowed and every bite tastes evenly seasoned.

Granny’s Kitchen Notes

From Betty Lou Gardner

I always make this ahead because it never tastes quite right the first hour. The onions need time to mellow, and the beans need time to soak up the dressing. This is one of those dishes that seems to show up whenever people are eating outside, and there is usually somebody standing over the bowl helping themselves to one more spoonful before supper is even served.
