Grilled Steak Tacos with Poblano Mango Salsa

I get Saveur magazine, a cooking magazine. The June-July issue has an ad for Beef-It's What's for Dinner. The featured recipe is from a rancher out of Big Sandy, Montana. Hete is the recipe:

Totale recipe time: 50-55 minutes. Serves 4

1 lb top sirloin steak cut 3/4 inch thick
2 medium poblano peppers
1 medium onion cut into 1/2 inch thick slices
2 cloves garlic minced
1 tsp ground cumin (you may want to use less, or more to taste)
1 medium mango, diced
1/4 cup chopped fresh cilantro
1/4 cup fresh lime juice
1/4 tsp salt (optional)
8 small corn tortillas (6-7inch diameter)
Fresh cilantro springs, lime wedges-optional

1. Place peppers and onion slices on BBQ grill-medium heat if gas grill or medium ash covered coals in using charcoal. Grill covered for 15 to 20 minutes or until onion is tender and pepper skins are blackened, turning occasionally. Place peppers in food-safe plastic bag, close bag. Set peppers and onion aside.

2. Meanwhile, combine garlic and cumin; press evenly onto beef steaks. Place steaks on grid over medium heat on BBQ grill. Grill covered 13 to 16 minutes or 8 to 13 minutes for medium rare to medium turning occasionally. Remove. Keep warm.

3. Remove and discard skins, stems, seeds from peppers when cool enough to handle. Chop peppers and onion. Combine chopped vegetables, mango, cilantro, lime juice and salt in medium bowl. Set aside.

4. Place tortillas on grid, grill, uncovered for 30 seconds on each side or until heated through and lightly browned.

5. Carve steaks into slices. Top tortillas with equal amounts of beef and mango salsa. Garnish with cilantro springs and lime wedges if desired.
