Finely chop the raw shrimp until it reaches a coarse, paste-like consistency and transfer to a mixing bowl.
Add the finely shredded cabbage, sliced green onions, grated ginger, minced garlic, sesame oil, tamari, salt, and pepper to the shrimp.
Stir the filling vigorously until the ingredients are well incorporated and the mixture becomes slightly tacky.
Submerge one rice paper sheet in a shallow dish of warm water for about 5 seconds until just pliable, then lay it flat on a damp cutting board.
Place a generous portion of the shrimp filling in the center of the rice paper, fold the bottom up, the sides in, and roll tightly to create a rectangular parcel.
Heat the avocado oil in a large non-stick skillet over medium heat.
Place the dumplings in the skillet, ensuring they do not touch, and sear for 3 to 4 minutes per side until the wrappers are golden and crispy and the shrimp is opaque.
