This grilled salmon sandwich is a delightful blend of flavors and textures, perfect for a quick yet satisfying meal. The combination of tender, flaky salmon with crisp lettuce and juicy tomato, all nestled between slices of toasted whole grain bread, makes for a nutritious and delicious sandwich.
If you don't usually cook with salmon, you might need to visit the seafood section of your supermarket. Make sure to get skinless fillets for ease of preparation. Additionally, dijon mustard might not be a pantry staple for everyone, but it adds a wonderful tangy flavor to the sandwich.

Ingredients For Grilled Salmon Sandwich Recipe
Salmon: A rich source of protein and omega-3 fatty acids, perfect for grilling.
Whole grain bread: Provides a hearty base for the sandwich, adding fiber and nutrients.
Olive oil: Used to brush the salmon, helping it to cook evenly and adding a subtle flavor.
Salt: Enhances the natural flavors of the salmon.
Freshly ground black pepper: Adds a bit of heat and complexity to the seasoning.
Mayonnaise: Adds creaminess to the sandwich spread.
Dijon mustard: Brings a tangy, slightly spicy flavor to the spread.
Shredded lettuce: Adds a refreshing crunch to the sandwich.
Tomato: Provides juiciness and a slight sweetness to balance the flavors.
Technique Tip for This Recipe
To achieve perfectly grilled salmon, make sure to preheat your grill to medium-high heat. This ensures that the fish cooks evenly and develops a nice char. When brushing the salmon fillets with olive oil, be generous but not excessive to prevent sticking and to enhance the flavor. Seasoning with salt and freshly ground black pepper right before grilling helps to lock in the moisture and flavor. For an extra layer of taste, consider adding a squeeze of lemon juice after grilling. When toasting the bread, keep a close eye to avoid burning; a light golden brown is perfect. Mixing mayonnaise and dijon mustard creates a creamy, tangy spread that complements the richness of the salmon. Finally, use fresh lettuce and tomato slices to add a crisp, refreshing contrast to the warm, savory sandwich.
