In a bowl, whisk eggs, 1 tbsp. cold water and 1/8 tsp. salt. Lightly coat a medium nonstick skillet with cooking spray; heat over medium. Add eggs; cover and cook until just firm, about 2 minutes. Transfer to a cutting board; slice into 10 strips. Create 5 skewers by alternating rolled-up egg strips, tomatoes, cheese and avocado. Sprinkle with cilantro and remaining 1/8 tsp. salt.
