This tasty sandwich is perfect for a midday meal. Its high-protein content will help you feel full and satisfied throughout the afternoon.
Two 6-ounce pouches water-packed tuna
1/3 cup light mayonnaise
2 tablespoons finely chopped red onion
Pinch of salt and pepper to taste (optional*)
4 slices of ripe tomato
8 slices low-fat Swiss cheese
In a bowl, mix together tuna, mayonnaise and red onion. Add a pinch of salt and pepper to taste, if needed.*
Assemble tuna melts by placing the tomato slices on a baking sheet, placing a scoop of tuna salad in the center of each and covering with two slices of cheese.
Broil 6 to 8 minutes, until cheese starts to brown, and is bubbling around the edges.
Transfer to serving plates.
Higher protein option
You can increase the amount of protein by whisking a couple of tablespoons of unflavored whey protein powder* into your mayonnaise before mixing it into your tuna (then add the remaining ingredients).
