Put the sweetcorn, beans, celery, onion and coriander in a large bowl, and mix well. Blend the salsa and vinegar together. Pour over the salad, and toss well.
Cover and refrigerate for at least 1 hour before serving.
Points to remember
Canned Black Beans:
If using canned black beans, drain and rinse them thoroughly under cold water to remove excess sodium.
Use fresh and high-quality vegetables to enhance the flavor of the salsa.
Ensure the salsa used is fresh and free from any signs of spoilage. Check the expiration date if using store-bought salsa.
Be mindful of any allergies to ingredients. Consider offering alternatives or omitting ingredients based on dietary restrictions.
