Begin by rinsing the sushi rice under cold water until the water runs clear. Cook the rice in a rice cooker or a pot according to package instructions. Once cooked, let it cool slightly.
In a small bowl, mix together the vinegar, sugar, and salt until dissolved. Gently fold this mixture into the warm rice. Be careful not to mash the grains; you want to keep them fluffy.
While the rice is cooling, prepare your vegetables. Julienne the cucumber, bell pepper, and carrots into thin strips. Blanch the bean sprouts in boiling water for about 2-3 minutes until they are tender, then drain and rinse under cold water. In a bowl, combine the bean sprouts with chili paste and soy sauce for flavor.
Place a sheet of nori on your sushi mat, shiny side down. Spread a thin layer of the seasoned rice over the nori, leaving about 2 inches at the top edge. Layer the vegetables and flavored bean sprouts on top of the rice.
Using the sushi mat, carefully roll the kimbap away from you, applying gentle pressure to form a tight roll. Make sure to tuck in the filling as you roll. Once fully rolled, use a sharp knife to slice the kimbap into bite-sized pieces.
Arrange the sliced kimbap on a platter and serve with your favorite dipping sauce or a side of pickled vegetables. Enjoy your homemade Veggie Kimbap with Bean Sprouts!
