Mushroom Steak Fajitas

12 ounces sirloin or other boneless steak (about 3/4-inch thick)
3 cups sliced cremini mushrooms
1 tablespoon no-salt fiesta lime seasoning (divided)
1 tablespoon olive oil
1 cup green bell pepper slices

8 whole-wheat tortillas (6-inch)
1 medium tomato (diced)
2 cups shredded iceberg lettuce

Slice beef across the grain into 1/4-inch strips. Place in a medium bowl with 1/2 tablespoon fiesta lime seasoning; toss to coat.
Place mushrooms, peppers, and onion and remaining fiesta lime seasoning in a large bowl; toss to coat.
Heat oil in large, non-stick skillet. Add beef strips; cook about 3 to 4 minutes. Remove from skillet.

Add beef back to skillet and sauté mixture 1 to 2 more minutes.
