Cook your shrimp for 3-4 minutes on each side, or until the shrimp are cooked through. Once cool, cut in half lengthwise to have two shrimp pieces. Set aside.
Assemble rolls - start by adding 3 shrimp halves, seared side down, to the bottom third of a prepared rice paper wrap. Top with spring mix, cucumber, and red noodles. Fold like a burrito - move the bottom of the wrapper over the filling ingredients and pull towards you to wrap tightly.
