No-Mess Steak Fajitas

Ingredients

• 2 tablespoons fresh lime juice
• 1 tablespoon olive oil
• 2 teaspoons bottled minced garlic
• 1 teaspoon chili powder
• 1 teaspoon ground cumin
• 1/2 teaspoon salt, divided
• 1 1/4 pounds top sirloin steak, trimmed and cut into thin slices
• 1 medium green bell pepper, halved, seeded, and thinly sliced
• 1 large red onion, halved and thinly sliced
• Cooking spray
• 3 tablespoons chopped fresh cilantro
• 10 (8-inch) low-fat whole wheat flour tortillas (such as La Banderita)
• Fat-free sour cream (optional)

Preparation

1. 1. Combine first 5 ingredients and 1/4 teaspoon salt in a small bowl, stirring with a whisk; pour into a large zip-top plastic bag. Add steak, bell pepper, and onion; seal bag, and marinate in refrigerator at least 6 hours, turning bag occasionally.
2. 2. Preheat oven to 450°.
3. 3. Transfer steak mixture to a heavy-duty foil bag that has been coated with cooking spray. Roll up bag tightly. Place bag on a jelly-roll pan or baking sheet. Bake at 450° for 40 minutes.
4. 4. To serve, carefully cut a slit in bag. Sprinkle steak mixture evenly with remaining 1/4 teaspoon salt and cilantro; toss well. Divide mixture evenly among flour tortillas. Serve with fat-free sour cream, if desired.
