Nora’s Smart Tips for the Ultimate Tuna Melt

Looking to take your Tuna Melt to the next level? These tried-and-true tips will help you boost flavor, texture, and nutrition—without adding extra time in the kitchen.

• Swap in Greek yogurt for part (or all) of the mayo. It adds extra protein and creaminess with fewer calories and more gut-friendly probiotics. You’ll barely notice the difference in taste—but your body will appreciate it.
• Choose sprouted grain or high-fiber bread for a nutrient-dense base. These types of bread are more digestible and keep you feeling full longer, making them a great option for sustained energy throughout the day.
• Add a flavor punch with extras like sliced pickles, arugula, or Dijon mustard. These small touches can completely elevate the sandwich, bringing brightness and complexity to every bite.
• Prefer a crispier finish? Toast your bread separately before assembling the sandwich. This way, you get golden, crunchy edges that hold up beautifully against the warm, melty filling.
• Make a double batch of the tuna salad. It stores well in an airtight container for up to 4 days and makes for quick, no-stress lunches. Serve it on crackers, in wraps, or over greens for variety.
