Rinse the sushi rice until the water runs clear.

In a large bowl, combine the rinsed rice with water.

Cover the bowl with a lid and let it sit for 30 minutes.

Cook the rice according to the package instructions.

Once cooked, transfer the rice to a large bowl and let it cool slightly.

In a small bowl, combine the rice vinegar, sugar, and salt. Pour the mixture over the cooled rice and gently fold it in until the rice is evenly coated.

Place a nori sheet on your sushi rolling mat with the shiny side facing down.

Wet your hands slightly to prevent the rice from sticking.

Spread a thin layer of sushi rice over the nori sheet, leaving a small space at the top for sealing.

Place the avocado, cucumber, imitation crab meat, and carrots in a line near the bottom of the rice.

Roll the sushi tightly, using the rolling mat to guide you.

Moisten the top of the nori sheet with water to seal the roll.

Sprinkle the roll with sesame seeds.

Slice the roll into 8 equal pieces.

Garnish with sliced avocado and serve immediately.

For a more flavorful sushi roll, add some wasabi paste or pickled ginger to the filling.

You can also add other ingredients to the filling, such as cooked shrimp, salmon, or tuna.

If you're new to making sushi, practice rolling the rice into a tight log before adding the filling.

For a fun twist, try using different types of nori sheets, such as seaweed sheets with a flavor or color.
