25 Minutes Total Time

6-8 Servings


  • 1 medium cucumber, sliced into ½ inch rounds (I used an English cucumber from Trader Joe’s)
  • 5 oz. can Genova Yellowfin or Albacore Tuna in Olive Oil, drained
  • 3 tablespoons store bought pesto
  • Freshly ground black pepper, to taste
  • 7 cherry tomatoes, halved
  • 7 basil leaves
  • 14 mini mozzarella balls (or you can just make small round mozz circles if you can’t find the balls)
  • 1 cup balsamic vinegar
  • 1 tablespoon sugar (any will work)


  1. Add balsamic vinegar and sugar to a small saucepan and place over medium high heat. Bring mixture to a boil, then reduce to medium low and simmer for 15-20 minutes, stirring every so often until the balsamic vinegar turns into a thick syrup like consistency. Remove from heat and set aside. Note: if the mixture hardens up after removing from heat, just reheat it over a low heat.
  2. While the balsamic vinegar is boiling, add the tuna, pesto and freshly ground black pepper to a small bowl; stir to combine.
  3. Place about a ½ tablespoon of tuna pesto mixture on each cucumber round. Top with mozzarella ball, cherry tomato half, and small basil leaf and secure with a toothpick.
  4. Transfer all to a platter. Drizzle with balsamic reduction and serve immediately. Makes 14 bites.
