Just as everyone has some form of a taco in their country (wrap, spring roll, lettuce wrap), everyone has some form of sushi (sandwich, rice bowl, kimpop). I LOVE kimpop. My mom used to pack these for me when I was kid to take to school since I wouldn't touch a sandwich. You can put whatever you want in these. My family always uses hot dogs (free of artificial gunk), eggs, cucumber, and pickled radish. I also like to add kimchi into mine and it makes it uber delicious. They can be packed with protein for a good, healthy snack, or however you like it. For my sister-in-law, who isn't a fan of meat, we just use cucumbers and eggs and it's just as wonderful. You can also use brown rice instead of white rice, a combination, or no rice to be a little more paleo.
8 cups cooked rice
1/3 cup distilled white vinegar
1 T salt
1 T sesame oil
2 T sesame seeds
12 sheets of plain seaweed (remember, this makes 12 rolls so you can half all of this)
8 hot dogs, sliced into long skinny pieces and sauteed in pan until slightly cooked
8 eggs, whisked in bowl and fried into thin sheets
1 cucumber (sliced into long skinny pieces)
1 "Dakwan" radish sliced into long skinny pieces (pickled radish you can find at any oriental market)
Mix all ingredients from rice down to sesame seeds together. Spread a big spoonful of rice onto seaweed sheet until sheet is covered, but don't use a ton of rice. Add rest of ingredients lengthwise in 1 row on sheet, then roll and slice into about 1/2 inch pieces and heat your heart out!
