Chic's 3 dollar dinners brings you these delicious Avocado Tuna Melts! With just 12 bucks you can feed a family of 4! Tuna sandwiches just got an upgrade!
In a large bowl, combine the tuna, red onion, scallions, parsley, lemon juice, olive oil, mustard (if using), salt and black pepper. Mix to evenly combine.
Toast the bread and arrange on a baking sheet. Top each bread with 2 slices of tomato, and a couple slices of avocado. Divide the tuna among each sandwich, piling it on top of the tomato and avocado.
Lay a slice of cheese on top of the tuna and place under the broiler for a few seconds, just until melted. Serve right away and enjoy!
