Mini Triple-Decker Tuna Melts Ingredients
For the Tuna Salad
- Flaked Tuna – This is your main protein source; choose canned tuna for maximum convenience.

- Dijon Mustard – Introduces a tangy flavor; you can use yellow mustard if you prefer something milder.
- Lemon Juice – Brightens up the salad; freshly squeezed is ideal, but bottled will do in a pinch.
- Celery – Provides a refreshing crunch; replace it with chopped pickles for a tangier taste.
- Red Onion – Adds a nice sharpness; chop finely to keep the flavors balanced, or substitute with green onions for a milder bite.
For the Sandwich
- Sourdough Bread – The crunchy base of this melt; opt for gluten-free bread to accommodate dietary restrictions.
- Cheddar Cheese – Melts perfectly and adds richness to each bite; feel free to exchange it for mozzarella or your favorite cheese variety.

These Mini Triple-Decker Tuna Melts are a fantastic option for meal prep! You can prepare the tuna salad up to 24 hours in advance by mixing flaked tuna, mayonnaise, Dijon mustard, lemon juice, celery, and red onion (keeping it tightly sealed in the refrigerator).
