Denise's Fa-heets

My neighbor made us these fajitas of love and used chicken instead of flank steak. Super yummy!!

• 1 flank steak (1 pound)
• 1 Spanish onion (about 9 ounces), sliced
• 1 sweet red pepper, cored, seeded and sliced
• 1 clovegarlic, finely chopped
• 1/4 cupfresh lime juice
• 1 tablespoonolive oil
• 1 tablespoonbalsamic vinegar
• 2 tablespoonschopped fresh cilantro
• 1/4 teaspoonground cumin
• 1/8 teaspoonsalt
• 8 flour tortillas (8-inch), warmed
• Pico de gallo (optional)

Combine all ingredients (not the tortillas!) and let marinade for a couple of hours. Cook up the meat and peppers and serve in warm tortillas with salsa, sour cream, cheese… Deliciouso!
