1

In a bowl, combine 2 cans drained tuna in water (5 oz), 2 tbsp mayonnaise, 1 finely diced celery stalk, 2 tbsp finely diced red onion, 1 tsp Dijon mustard, 2 tsp fresh lemon juice, 1/4 tsp kosher salt, and 1/4 tsp freshly ground black pepper. Mix well and taste for seasoning.

Questions

Can I make Tuna Melt dairy-free?

Yes. The dairy in this entry is 2 tsp unsalted butter, softened, 2 oz sharp cheddar cheese, sliced. Swap the butter for olive oil where it melts, or a plant-based block butter where it is creamed; the cheese for a plant-based melting cheese (expect a milder flavor). The richness shifts slightly, but the method does not change.

Can I make Tuna Melt gluten-free?

Yes. The gluten in this entry is 2 slices sourdough bread, thick slices. Swap the bread or crumbs for a gluten-free loaf or gluten-free panko. Everything else proceeds as written.

How long does Tuna Melt keep?

Refrigerate leftovers within two hours and eat them within two days (seafood turns fast). Reheat gently on the stovetop.

Can I halve or double Tuna Melt?

Yes. As written it serves 2. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. When doubling on the stovetop, use your widest pan or work in two batches so the food sears instead of steaming.
