Joe & the Juice Tunacado Sandwich — The Viral $15 Sandwich, Made at Home
Prep time: 15 min Cook time: 5 min Servings: 4
A single TikTok review pushed a sandwich called the Tunacado to 11.7 million views in September 2023. The video showed someone eating a Joe & the Juice sandwich that most of the internet had never heard of: a pressed-crispy flatbread loaded with smooth tuna mousse, vegan basil pesto, fresh avocado, and tomato. Copycat recipes appeared within days. The sandwich, which costs $13 to $17 at Joe & the Juice locations across the United States, turned out to be deceptively simple — and genuinely good.
There are two things that make the Tunacado different from a tuna sandwich you might throw together at home. First, the tuna mousse: not flaked, not chunky, but mixed until it’s nearly smooth and spreadable — a texture that holds up in the sandwich without falling out in bites. Second, the bread: pressed on a panini grill until it’s very flat, deeply golden, and crackly enough to provide structural support for the avocado and tuna without turning soggy. Get both of those right and the home version is essentially identical to the original.
The Tuna Mousse
Start with two cans of tuna in water — not oil-packed, which makes the mousse greasy rather than clean. Drain aggressively: the most common home-cook mistake is under-draining, which leads to a watery mousse that seeps into the bread. Wrap the drained tuna in a dish towel and squeeze. You should press out 2 to 3 tablespoons of liquid after the initial drain.
Mix the dry tuna with mayonnaise, Dijon mustard, drained capers, lemon juice, lemon zest, fresh dill, and finely minced red onion. Stir vigorously for a full 2 minutes — longer than feels necessary. The goal is to break down the tuna flakes almost completely, producing a dense, cohesive paste rather than a loose salad. The capers, lemon, and Dijon do the flavor work; the mixing does the texture work.
The Vegan Pesto
Joe & the Juice uses pesto with no Parmesan, keeping the entire sandwich vegan except for the mayo. Blend basil, toasted pine nuts, a small garlic clove, and olive oil until smooth. The result is brighter and more herbaceous than traditional Genovese pesto — you taste the basil more directly without the dairy richness muting it. If you prefer traditional pesto, add 2 tablespoons of Parmesan; the sandwich still works, it just diverges from the original.
The Pressed Bread
The Tunacado’s texture depends entirely on the bread being pressed flat and very crispy. A soft roll produces a completely different sandwich — one that absorbs moisture and loses its structure within minutes. Brush both cut sides of ciabatta rolls or focaccia rectangles with a little olive oil and press them in a panini press or under a heavy cast iron skillet over medium-high heat until deeply golden and compressed to half their original thickness. This step takes 3 to 4 minutes and is non-negotiable.
Assemble: spread pesto on both halves, layer tomato, then tuna mousse, then avocado. Close and serve immediately while the bread is at its crunchiest.
