Introduction

The Tunacado Sandwich is a creamy and flavorful combination of tuna, avocado, and fresh ingredients wrapped in crispy flatbread. Inspired by the viral Joe & The Juice recipe, this sandwich is perfect for a quick lunch or light dinner that feels both fresh and satisfying.

The dish shows an open flatbread sandwich on a white plate, set on a white marbled background. The flatbread is folded in half, with one half spread with a green pesto sauce that has a coarse texture and some charred dark spots on the bread. The other half has three layers: a bottom layer of white creamy spread with green herbs mixed in, topped by bright red tomato slices, and finished with creamy green avocado slices arranged side by side. The colors contrast well with the lightly toasted flatbread. photo taken with an iphone --ar 4:5 --v 7

Ingredients

5 oz can tuna
3 tbsp mayo
1/2 small lemon, juiced (or 1/4 large lemon)
1 tbsp chopped fresh dill
1/2 tbsp capers, drained
1 tsp Dijon mustard
Salt
Black pepper
2 thin slices of flatbread
1 tbsp pesto
Olive oil
Tomato slices
Avocado slices

Instructions

Step 1: Add the tuna to a small mixing bowl and thoroughly smash it with a fork. The more mashed it is, the creamier the tuna mixture will become.
Step 2: Add the mayo, lemon juice, fresh dill, capers, and Dijon mustard to the tuna. Combine well, then season with salt and black pepper to taste. Set aside.
Step 3: Heat olive oil in a large pan over medium heat. Add the flatbread slices and fry both sides until golden brown and crisp. Alternatively, toast the flatbread slices.
Step 4: Spread the pesto on one slice of the flatbread. On the other slice, layer the tuna mixture, tomato slices, and avocado slices. Press the two slices together to form the sandwich.
Step 5: Serve immediately and enjoy your fresh and creamy Tunacado Sandwich!

Tips & Variations

For extra flavor, add a few thin red onion slices or a handful of arugula inside the sandwich.
If you prefer a lighter mayo alternative, try Greek yogurt or mashed avocado in the tuna mix.
Use multigrain or sourdough bread if flatbread isn’t available, adjusting toasting time accordingly.
To make it spicier, add a dash of hot sauce or crushed red pepper flakes to the tuna mixture.

Storage

If you have leftovers, store the tuna mixture separately in an airtight container in the refrigerator for up to 2 days. Assemble the sandwich fresh to maintain crispness in the bread. Reheat toasted bread briefly in a pan or toaster, but avoid warming the tuna mix.

FAQs

Can I use fresh tuna instead of canned tuna?

Fresh tuna can be used if cooked and flaked properly, but canned tuna offers convenience and a ready-to-use texture best suited for this creamy sandwich.
