Creating Nigerian Salad is simple when you follow these steps:

1. Prepare the Vegetables: Wash and cut all the vegetables (lettuce, carrots, cucumber, bell peppers) into small, manageable pieces.
2. Cook the Peas: If using fresh green peas, boil them in salted water for about 5 minutes until tender. Then drain and set aside to cool.
3. Shred the Carrots: Use a grater or food processor to shred the carrots. This will make them easier to mix with the other ingredients.
4. Boil the Eggs: Place eggs in a pot, cover with water, and bring to a boil. Let them simmer for 10-12 minutes, then cool in ice water before peeling and chopping.
5. Combine Ingredients: In a large bowl, mix the chopped lettuce, shredded carrots, diced cucumber, sweet corn, cooked green peas, chopped eggs, and diced onions.
6. Prepare the Dressing: In a separate bowl, combine mayonnaise, mustard, lemon juice (if using), sugar (if using), and salt and pepper. Adjust the seasoning as per your taste.
7. Mix Salad and Dressing: Pour the dressing over the salad mixture and toss gently to ensure everything is coated evenly.
8. Chill: Let the salad chill in the refrigerator for about 10-15 minutes for flavors to meld.
9. Serve: Once chilled, serve the Nigerian Salad in a large dish or individual bowls.

By following these steps, you will have a vibrant and delicious Nigerian Salad that’s ready to be enjoyed!
