A high-protein tuna melt is perfect for lunch, dinner, or even a post-workout meal—offering convenience, flavor, and nutrition in one.
Ingredients for High-Protein Tuna Melt
Tuna Salad Base
- 2 cans of tuna in water, drained (~10 oz / 280g)
- 2 tbsp Greek yogurt (instead of mayo for extra protein and lower fat)
- 1 tsp Dijon mustard
- 1 tbsp finely chopped red onion
- 1 tbsp celery, finely chopped
- Salt and pepper to taste
- Optional: a squeeze of lemon juice for brightness
Cheese Layer
- 1/2 cup shredded part-skim mozzarella (or cheddar for stronger flavor)
- 2 slices high-protein bread (or whole grain / low-carb bread)
Optional Additions
- Sliced tomato or avocado
- Fresh spinach or arugula
- Pickles or jalapeños for extra flavor
Pro Tip: Using Greek yogurt instead of mayonnaise reduces fat and boosts protein without compromising creaminess.
Step-by-Step Instructions
Step 1: Prepare the Tuna Salad
- Drain the canned tuna thoroughly to remove excess water.
- In a medium bowl, combine tuna, Greek yogurt, Dijon mustard, red onion, and celery.
- Season with salt, pepper, and optional lemon juice.
- Mix until creamy but still slightly chunky for texture.
Tip: Taste and adjust seasoning before assembling the melt.
Step 2: Prepare the Bread
- Use high-protein or whole grain bread to boost protein content and fiber.
- Lightly toast the bread slices for a firmer base and to prevent sogginess from the tuna salad.
Step 3: Assemble the Tuna Melt
- Spread a generous layer of the tuna salad onto each slice of toasted bread.
- Top with shredded cheese (mozzarella, cheddar, or your choice).
- Add optional toppings such as sliced tomato, spinach, or avocado for extra flavor and nutrients.
Step 4: Melt the Cheese
- Preheat a skillet over medium heat or use an oven/broiler.
- Skillet method: Cover with a lid and cook 3–5 minutes until cheese melts.
- Oven method: Place assembled melts on a baking sheet and broil for 3–5 minutes, watching carefully to avoid burning.
Step 5: Serve
- Remove the melts from heat and serve immediately.
- Optional garnish: sprinkle fresh parsley or black pepper.
Serving Suggestion: Pair with a side salad or steamed vegetables for a balanced meal.
