Top Tips

Start with good-quality canned tuna and a flavorful pesto sauce. Fresh, high-quality ingredients will make a significant difference in the taste of your sandwich.

This sandwich tastes amazing with avocados, but that day I didn’t have any avocados on hand.

If you have the time and ingredients, consider making your own pesto sauce. Homemade pesto often tastes fresher and more vibrant than store-bought varieties.

Lightly toasting the bread can add a pleasant crunch to your sandwich and prevent it from becoming soggy.

When assembling the sandwich, layer the ingredients strategically. Place the lettuce or greens close to the bread to create a barrier between the moist tuna mixture and the bread, helping to prevent it from becoming soggy.

Get creative with your toppings! I threw in some fiery Thai chili sauce and fresh spinach leaves for an extra flavor punch – but the choice is yours to sauce and veggie it up!

Explore different types of bread to find your favorite. Ciabatta, baguette, sourdough, or whole-grain bread can all work well.

If you plan to take your pesto tuna sandwich with you, wrap it tightly in parchment paper or foil to prevent it from falling apart or getting squished.

If you enjoy cheese, consider adding a slice of mozzarella, provolone, or Swiss for a creamy and melty touch.
