Mediterranean Tuna Salad

This tuna salad is so simple yet so full of flavor! Canned tuna is on our list of pantry staples because it is full of protein and omega-3 fatty acids, which reduce inflammation and support brain and heart health. This salad is also loaded with colorful veggies providing fiber and antioxidants. The olive oil in the dressing adds an additional serving of heart-healthy fats.

This tuna salad keeps well in the fridge for several days so make it in advance and have it for lunch all week long!
