These open-faced sandwiches make a simple dinner and are perfect for a busy night. You can top the melts with different cheeses, such as Swiss or Monterey Jack, or leave off the tomato or avocado, according to your family’s tastes.

Servings 4 servings


  • 12 oz. chunk light tuna in water drained
  • 2 Tbsp. reduced-fat mayonnaise (or use any variety),
  • 1 stalk celery finely diced
  • 4 slices sourdough bread (use wheat/gluten-free if needed)
  • 1 avocado thinly sliced
  • 1 tomato thinly sliced
  • 4 slices Cheddar or Muenster cheese


  • Preheat the oven to 350 degrees and line it with parchment paper for easier cleanup, if desired.
  • In a small bowl, combine the tuna, mayonnaise, and celery and mix it thoroughly.
  • Lightly toast the bread. Spread about 1/4 of the tuna salad on each piece of sourdough toast and top it with slices of avocado and tomato and a slice of cheese.
  • Carefully transfer the open-faced sandwiches to the baking sheet and bake them for about 5 minutes, or until the cheese is melted. Slice the sandwiches in half to serve them.


Do Ahead or Delegate: Dice the celery, prepare and refrigerate the tuna salad, slice the bread if necessary, slice the tomato, slice the cheese if necessary and refrigerate.
Scramble Flavor Booster: Add slivered almonds or sunflower seeds, black pepper, and/or fresh lemon juice to the tuna.
Tip: If you like your cheese browned on top, stick the sandwich under the broiler for a minute or two. Just watch it carefully so it doesn’t burn.
