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.


Step 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.
Step 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.
Step 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.
Step 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.
