In a small saucepan, combine lime juice, zest, onion, garlic, vinegar, mango, olive oil, and TABASCO® Habanero Sauce over medium heat. Bring mixture to a simmer and let cook for 10 minutes. Remove from the heat, season with salt and pepper, and let cool.
Cut tuna into 1/4-inch pieces and place in a medium sized bowl. Add the scallions, egg, and breadcrumbs. Season with salt and pepper and mix well. Form into 6 patties and brush them with the oil.
Grill on foil or broil burgers 2-4 minutes per side or until cooked to desired doneness. Serve on rolls with mango mojo on top.
