What you'll need

Instructions

  1. In a medium bowl, combine the drained tuna, avocado oil mayo, Dijon mustard, celery, red onion, lemon juice, sea salt, and black pepper. Fold gently until evenly mixed.
  2. Preheat oven to 375°F (or broil setting). Slice the sub rolls lengthwise, leaving a hinge, and open them on a baking sheet.
  3. Spoon the tuna mixture evenly down the center of each roll.
  4. Lay 2 slices of provolone over the tuna in each sub.
  5. Bake or broil for 5–7 minutes until the cheese is melted and bubbly and the bread is toasted on the cut edges.
  6. Remove from oven and immediately top with shredded romaine, tomato slices, and cucumber.
  7. Drizzle a little olive oil over the fresh vegetables, close the subs, and serve hot.

FAQ

What is the best clean-label canned tuna brand?

Wild Planet and Safe Catch are the gold standards — both are wild-caught, tested for mercury, and packed in water with no fillers. Safe Catch tests every fish individually for mercury content.

Can I make this cold as a regular tuna sub?

Absolutely — skip the baking step and serve the tuna mixture cold on toasted bread. Add a slice of cheese or leave it off for a lighter sandwich. It's closer to a classic tuna salad sub that way.
