Prepare the egg:
Beat eggs and cook in a lightly greased pan until set. Slice into thin strips.
Prep vegetables & meat:
Cut cucumber, carrots, pickled radish, and Spam into thin strips. Remove cucumber seeds if desired.
Cook carrots & Spam:
Toss carrots with 1 tablespoon salt and let sit for 15 minutes. Squeeze out excess liquid and sauté for about 4 minutes.
In the same pan, fry Spam for about 1 minute per side until golden brown.
Prepare rice:
Lightly season cooked rice with sesame oil and a pinch of salt (optional).
Assemble kimbap:
Place a sheet of seaweed on a bamboo mat. Spread a thin layer of rice evenly, leaving about 1 inch (2 cm) at the top edge.
Add fillings:
Arrange egg, vegetables, radish, and Spam in rows across the center.
Roll:
Lift the mat and roll tightly, pressing firmly as you go. Seal the edge with a few grains of rice if needed.
