Ingredients List

Here’s everything you’ll need to make this classic salad:

• 1 can (8 ounces) cut green beans, drained

• 1 can (8 ounces) cut wax beans, drained

• 3/4 cup canned kidney beans, rinsed and drained

• 1/4 cup chopped onion

• 2 tablespoons sugar

• 2 tablespoons white vinegar

• 1 tablespoon canola oil

• 1/8 teaspoon black pepper

This balance of sweet, tangy, and savory creates the signature flavor that defines a traditional 3-bean salad.

Step-by-Step Instructions

Step 1: Combine the Beans and Onion

In a medium bowl, combine the green beans, wax beans, kidney beans, and chopped onion. Gently mix until the beans are well distributed.

Step 2: Make the Dressing

In a separate small bowl, whisk together the sugar, white vinegar, canola oil, and black pepper. Whisk until the sugar dissolves and the vinaigrette is smooth.

Step 3: Dress the Salad

Pour the vinaigrette over the bean mixture and stir gently to coat all ingredients evenly.

Step 4: Chill and Serve

Cover the salad with plastic wrap or transfer it to an airtight container. Refrigerate for at least 1 hour—but ideally overnight—for the flavors to develop fully.

Kitchen Equipment Needed

No special gadgets required—just basic kitchen tools:

• Medium mixing bowl

• Small bowl for dressing

• Whisk or fork

• Measuring spoons

• Can opener

• Spoon or silicone spatula

• Storage container or plastic wrap

Optional: A glass mason jar can be used for shaking the dressing instead of whisking.

Storage Instructions

This salad stores exceptionally well. In fact, it tastes better the next day after the beans have absorbed the vinaigrette.

Storage tips:

• Refrigerator: Store in an airtight container for up to 5 days.

• Freezing: Not recommended. The beans will become mushy and the dressing will separate when thawed.

Before serving leftovers, give the salad a quick stir to redistribute the dressing.

Tips, Shortcuts & Variations

Tips:

• Rinse canned beans thoroughly to remove excess sodium and metallic taste.

• Chill for at least an hour to allow the flavors to develop—overnight is even better.

• Cut onions finely so they don’t overpower the beans in each bite.

Shortcuts:

• Use pre-chopped onions from the produce section to save time.

• Mix the dressing in a jar with a lid and shake vigorously instead of whisking.

Variations:

• Add more beans: Try garbanzo beans, black beans, or cannellini beans.

• Fresh herbs: Add chopped parsley or dill for brightness.

• Crunchy extras: Toss in chopped celery, bell peppers, or even corn.

• Spicy twist: Add red pepper flakes or a splash of hot sauce to the dressing.

Nutritional Benefits

This salad is more than just tasty—it’s nutrient-dense:

• Kidney beans are high in fiber and plant-based protein.

• Green and wax beans add color, crunch, and vitamin A.

• Canola oil provides a heart-healthy fat source.

• Vinegar may help with blood sugar control and digestion.

The best part? You get all this goodness with very little prep time.

• Picnic spreads: Serve alongside deviled eggs, pasta salad, or sandwiches.
