Ingredients

Instructions

  1. Step 1: In a bowl, mix drained tuna, mashed avocado, chopped pickles, and lemon juice until well combined and creamy. Taste and adjust seasoning with a pinch of salt if needed.
  2. Step 2: Arrange cucumber slices on a plate. Spread a thin layer of tuna mixture onto each slice (about 1 tbsp per slice), then top with a small square of bread.
  3. Step 3: Place a thin slice of cheddar cheese on top of each bread square, then arrange the cucumber-tuna slices on a baking sheet lined with parchment paper.
  4. Step 4: Broil on high for 2-3 minutes until cheese is melted and bubbly, watching closely to prevent burning. Serve immediately while warm.
