Number eight Ieuan Jones went over twice in Newport Gwent Dragons' bonus-point Amlin Challenge Cup win at Italian club Mogliano.
Centre Andy Tuilagi touched down first with Jones and wing Will Harries also crossing in the opening period.
Jones added the bonus-point score and Tom Prydie finished off the try-scoring and kicked for conversions.
However, Dragons lock Jevon Groves was sent off for a tip tackle in the 30th minute against their gutsy hosts.
