  • ¼ teaspoon sea salt

For the Sliders

Instructions

Step 1: Prepare the Tuna Mixture

In a medium bowl, combine:

  • Tuna
  • Greek yogurt
  • Dijon mustard
  • Celery
  • Red onion
  • Parsley
  • Garlic powder
  • Salt
  • Black pepper

Mix until smooth and evenly combined.

Taste and adjust the seasoning as desired.

Step 2: Slice the Apples

Slice them horizontally into rounds approximately ¼ inch thick.

Brush each slice lightly with lemon juice to help prevent browning and maintain freshness.

Select the largest slices to serve as the tops and bottoms of the sliders.

Step 3: Assemble the Sliders

Place one apple slice on a serving board.

Add a spoonful of tuna salad to the center.

Top with a small lettuce leaf if desired.

Place another apple slice on top to create a slider.

Repeat with the remaining ingredients.

Secure each slider with a decorative toothpick if needed.

Step 4: Serve

Arrange the sliders on a serving platter.

Garnish with fresh parsley.

Serve immediately while the apples are crisp and refreshing.

Why Apple Slices Make a Great Bread Alternative

Traditional sandwich buns can add significant amounts of refined carbohydrates and calories. Using fresh apple slices instead provides a naturally sweet and crunchy alternative while adding valuable nutrients.

Apples contribute:

  • Dietary fiber
  • Vitamin C
  • Antioxidants
  • Natural sweetness
  • Refreshing texture

The crispness of the apples perfectly balances the creamy tuna filling, creating a unique texture that’s both satisfying and delicious.
