My husband has made his own black bean salad, but it is more of a toss together whatever we have on hand thing than a recipe. He puts canned beans and canned corn in (unless we have leftover corn on the cob.) Then he adds chopped onion, chopped tomato, maybe some bell pepper if we have it on hand. He also tosses in some cilantro and then salt and pepper. He would dress it with an olive oil and citrus dressing. Hope that helps.
Here are some recipes that I found. Neither of these are mine, but here they are:
Black bean and corn salad:
Ingredients
1/3 cup fresh lime juice
1/2 cup olive oil
1 clove garlic, minced
1 teaspoon salt
1/8 teaspoon ground cayenne pepper
2 (15 ounce) cans black beans, rinsed and drained
1 1/2 cups frozen corn kernels
1 avocado - peeled, pitted and diced
1 red bell pepper, chopped
2 tomatoes, chopped
6 green onions, thinly sliced
1/2 cup chopped fresh cilantro (optional)
Directions
1 Place lime juice, olive oil, garlic, salt, and cayenne pepper in a small jar. Cover with lid, and shake until ingredients are well mixed.
2 In a salad bowl, combine beans, corn, avocado, bell pepper, tomatoes, green onions, and cilantro. Shake lime dressing, and pour it over the salad. Stir salad to coat vegetables and beans with dressing, and serve.
