Thai Tuna Burgers with Papaya Salsa are made with bright, healthy, fresh flavors that will kick start your summer or brighten your winter.
Place a large saute pan over medium-high heat. Pan sear serrano chiles about 4 minutes or until charred on all sides. Transfer to a bowl and cover with plastic wrap. Let stand for 5 minutes. This will make the skin easy to peel off. Remove as much skin as possible from peppers, cut in half, remove seeds, and dice remaining flesh.
Transfer diced peppers to a medium bowl. Add papaya, lime juice, cilantro, and red onion. Toss to combine.
Combine breadcrumbs, lemon zest, ginger, and salt in a food processor. Pulse until fine. Add tuna, basil, and cilantro. Pulse just until tuna is coarsely chopped -- do not puree. Form into 4-ounce patties.
Prepare a large nonstick pan with cooking spray and place over medium-high heat. Sear burgers on each side until desired doneness, about 2 minutes per side for medium rare.
Place cooked tuna burger on bottom bun, top with ¼ cup papaya salsa and top of bun.
