Start by draining your tuna well. Mix it in a bowl with mayo, finely chopped red onion, and honey or sugar if using. Stir until combined into a creamy, slightly sweet filling.
Slice the pickles lengthwise and scoop out the seeds carefully. Pat them dry with a paper towel to prevent the filling from becoming watery.
Add the chopped pickle seeds to the tuna mixture for extra crunch. Then, spoon the tuna salad into each pickle half evenly. Chill in the fridge or serve immediately for a refreshing snack.
