Tuna and eggs are both nutrient-dense ingredients. By swapping classic mayonnaise for lighter alternatives like sour cream or Greek yogurt, you can reduce added fats while retaining creaminess. Choosing whole wheat bread adds fiber and nutrients compared with white bread. When prepared with these healthier ingredient choices, a tuna egg sandwich provides protein, B vitamins, vitamin D, selenium, phosphorus, magnesium, and potassium.

What substitutes can I use instead of mayo?

Mayonnaise gives salads a rich, creamy mouthfeel, but there are several excellent substitutes that are lower in fat or add interesting flavor profiles. Try any of the following in tuna egg salad:

  • Sour cream: Smooth and tangy, sour cream creates a creamy dressing with a pleasant acidity.
  • Greek yogurt: Thick, protein-rich, and tangy—an excellent, nutritious mayo substitute.
  • Hummus: Adds creaminess and Mediterranean flavor thanks to tahini and garlic.
  • Pesto: Herb-forward and savory; pesto lends bright basil flavor and works well if you want a herby twist.
  • Mashed avocado: Naturally creamy and nutritious; season to taste to complement the tuna and egg.
