Best snack ever. The only problem is that you won’t be able to have just one!
Fortunately, this recipe makes a dozen sliders so you can afford to share one or two. These would be great at your next backyard barbeque. —Coley @ Coley Cooks

What You'll Need
  • 2/3 cup mayonnaise
  • 1 small shallot, minced
  • 1/4 cup minced dill pickles
  • 1 lemon, zested and juiced
  • 2 tablespoons capers, drained, rinsed and minced
  • 2 tablespoons finely minced parsley
  • freshly cracked pepper, to taste
  • 12 small slider rolls, sliced in half lengthwise
  • 2 tablespoons salted butter
  • 12 small pieces of little gem, bibb, or other delicate lettuce
  • 2 plum tomatoes, cut into 12 even slices
  • 1 pound skinless barramundi fillets, cut into 12 2-inch squares
  • 2 tablespoons blackening seasoning
  • 1 tablespoon vegetable oil
  • 12 toothpicks, for serving
  1. In a small bowl, whisk together the mayonnaise, shallot, pickles, lemon zest, lemon juice, capers, parsley and pepper, then cover and refrigerate until ready to serve.
  2. Melt butter in a large skillet over medium heat, then place the slider rolls in the pan cut side down. Cook until lightly browned and toasted, about 2 minutes. Remove to a serving platter and top each bottom roll with a small piece of lettuce and a slice of tomato.
  3. Coat the barramundi pieces all over with blackening seasoning. Heat vegetable oil in a large skillet (cast iron works best) over high heat. Cook the barramundi pieces until blackened on one side, about 2 minutes, then flip and cook on the other side until opaque throughout, about 1-2 minutes more.
  4. Place a piece of fish on each bun on top of the tomato, then spoon a generous amount of lemon tartar sauce on top. Place the top bun over the sauce and secure with a toothpick. Serve immediately.
