Begin by gathering all your ingredients. Hard-boil the eggs for 10 minutes, then cool and dice them. Seed and chop tomatoes, and slice the green onions finely.

In a mixing bowl, combine the diced eggs, chopped tomatoes, and sliced green onions. Season with salt and black pepper. Add mayonnaise and fold the ingredients together until uniformly coated.

Incorporate the crushed saltine crackers into the mixture, folding gently to maintain their crunch.

Transfer the salad to a serving dish and serve immediately to keep the crackers crunchy.
