The Creamy Ingredient Swap For Tuna Salad Without Mayo

If you're craving a tuna salad but need an egg-free mayonnaise substitute, swap the mayo for Greek yogurt to replicate the condiment's tangy flavor and creamy texture.

Mayonnaise owes its creaminess to eggs and oil and its subtle tartness to acidic ingredients, which can range from white vinegar or apple cider vinegar to lemon juice.

Greek yogurt is already creamy, thick, and a bit tangy, but adding a little Dijon mustard, a dash of lemon juice, and a drizzle of neutral oil can help it mimic mayo more closely.

When using Greek yogurt in dishes that call for mayo, buy an unsweetened variety, as sweetened yogurt adds a different flavor, and the sugar can be detrimental to your gut health.
