1-First, gather your ingredients and prepare them for mixing. Drain the 5 ounces of tuna and place it in a bowl. Dice the 2 tablespoons of red onion and chop the 1/4 cup of celery into small pieces. Slice the apple, removing the core, and set the slices aside. This step ensures everything is ready, making the process smooth and efficient.

2-Next, combine the prepared ingredients in your bowl. Add the drained tuna, 2 tablespoons of plain Greek yogurt or mayonnaise, the diced red onion, chopped celery, and 1 teaspoon of fresh lemon juice. Gently stir everything together until it’s well mixed, but be careful not to mash the ingredients too much. Season with salt and pepper to taste, adjusting as needed for your preference. If you’re adding optional items like chopped nuts or dried cranberries, mix them in now for extra flavor and texture.

3-Once your tuna mixture is ready, it’s time to assemble the bites. Take each apple slice and spoon a generous amount of the tuna salad on top. Make sure to cover the slice evenly for the best bite. Serve immediately to enjoy the crispness of the apple with the creamy tuna. For tips on keeping apples fresh, like drizzling them with lemon juice if you’re prepping ahead, this helps maintain that fresh appeal.
