Assemble spring rolls. Lay the spring roll wrappers on a flat surface. Lay out the veggies and the sauce near the wrappers like an assembly line. Take one of the wrappers and lay it flat. Near the bottom of the wrapper, layer on some of the bell peppers, carrots, cucumbers, cilantro, cabbage and a slight drizzle of the sauce. Roll it up by folding in the sides of the wrapper, then fold up the bottom over the veggies and continue rolling it up nice and tight like a burrito. Be careful not to overfill the wrapper or it may tear. Continue until you have made all of the spring rolls.
