Juicy and delish! Didn’t know to do this before, but this worked so well!
Lay the softened rice paper wrap on a clean kitchen towel or cutting board. Place a slice of cheese, a couple of tablespoons of beef mixture, some shredded lettuce, and a few pickle slices in the center of the wrap.
Fold the sides of the wrap over the filling, then roll it up tightly. Place the roll seam-side down on the prepared baking sheet. Repeat with the remaining wraps and filling.
