Being a pot of salted water to a boil and blanch the carrots and spinach until crisp-tender.
In a medium bowl, season the rice with the soy sauce, sugar and rice vinegar. Adjust the seasoning to your taste and add toasted sesame seeds if you wish; mix well.
Lay out the nori sheet and place ¾-1 cup of the seasoned rice on it. Use a rice paddle or your fingers to spread it evenly over ⅔ or the nori sheet.
Place your desired fillings in the middle of where you put the rice, then roll up that puppy (carefully).
Once your kimbap is rolled, you can rub a small amount of sesame oil over the nori to give shine and flavor. Slice the kimbap into slices or eat like a burrito if you are like me :)
Notes
Filling amounts for kimbap are vague, as you can choose how much/little to add to your kimbap.
