This recipe takes the grill to a new level. Grilled poblanos, onions and Top Sirloin Steak meet mangoes.
Place peppers and onion slices on grid over medium, ash-covered coals (over medium heat on preheated gas grill). Grill, covered, 15 to 20 minutes or until onion is tender and pepper skins are blackened, turning occasionally. Place peppers in foodsafe plastic bag; close bag. Set peppers and onion aside.
Meanwhile combine garlic and cumin; press evenly onto beef Top Sirloin Steak. Place steak on grid over medium, ash-covered coals. Grill, covered, 7 to 11 minutes (over medium heat on preheated gas grill, covered, 8 to 13 minutes) for medium rare (145°F) to medium (160°F) doneness, turning occasionally. Remove; keep warm.
Remove and discard skins, stems and seeds from peppers when cool enough to handle. Chop peppers and onion. Combine chopped vegetables, mango, chopped cilantro, lime juice and salt in medium bowl. Set aside.
Place tortillas on grid. Grill, uncovered, 30 seconds on each side or until heated through and lightly browned.
Carve steak into slices. Season with additional salt, as desired. Top tortillas with equal amounts of beef and mango salsa. Garnish with cilantro sprigs and lime wedges, if desired.
