In a medium skillet over medium heat, sauté the shrimp with garlic powder, ground ginger, sea salt, and black pepper until pink and opaque.
Remove shrimp from heat and chop into bite-sized pieces if they are large, then set aside.
In a large bowl, toss the shredded cabbage, carrots, and green onions with the tamari.
Fill a shallow dish with warm water and dip one rice paper sheet for about 10-15 seconds until pliable.
Lay the rice paper flat on a clean surface and place a portion of the shrimp and vegetable mixture in the center.
Fold the bottom of the rice paper over the filling, tuck in the sides, and roll tightly.
Wipe the skillet clean and add the toasted sesame oil over medium-high heat.
Place the rolls in the skillet and sear for 2-3 minutes per side until the exterior is crispy and golden brown.
Serve immediately while hot and crunchy.
