Trim spinach and carrots and blanch them in boiling water.
Beat the eggs, make a thin omelet over low heat, then cut into long strips.
Grill the ham in a pan and set aside.
On a sheet of seaweed, layer the omelet, spinach, carrots, and ham.
Instead of rice, spread cauliflower rice on the seaweed, add the ingredients, and roll tightly.
Cut the roll into bite-sized pieces.
