Cook rice according to package instructions until soft and fluffy. Let it cool slightly before assembling so it does not wilt the toppings.
Place eggs in a pot, cover with water, and bring to a boil. Cook for 6 to 7 minutes for a soft yolk. Cool in ice water, peel, and slice in half.
Slice cucumber, shred carrot, and cut avocado into wedges. Keep all ingredients ready for easy assembly.
Mix soy sauce, sesame oil, and lemon juice in a small bowl until well combined.
Add rice to bowls first. Layer smoked salmon, avocado, cucumber, carrots, and eggs on top.
Drizzle dressing over the bowl. Sprinkle sesame seeds and green onions. Serve fresh immediately.
