Combine 1/2 cup salsa, orange juice, cilantro, chili powder and 1 tablespoon orange peel in small bowl. Place beef steaks and salsa mixture in food-safe plastic bag; turn steaks to coat. Close bag securely and marinate in refrigerator 6 hours or as long as overnight, turning occasionally.
Remove steaks from marinade; discard marinade. Heat large nonstick skillet over medium heat until hot. Place steaks in skillet; cook 11 to 13 minutes for medium rare (145°F) to medium (160°F) doneness, turning occasionally.
Meanwhile, cook eggs as desired. Keep warm.
Combine remaining 1/2 cup salsa and 1 teaspoon orange peel. Carve steaks into thin slices; season with salt and pepper, as desired. Evenly place steak slices and egg on each tortilla. Top with salsa mixture and avocado slices. Serve with lime wedges, if desired.
