Blues recovered to show of their attacking potential with four tries in the second half, including one for British Lion Alex Cuthbert, to salvage a consolation bonus point.
And captain Sam Warburton insists taking on the reigning European champions is the ideal opportunity to prove a point. Warburton said: "It's important we bounce back from that loss and restore some pride.
"Many players worked hard for this club to gain a good reputation and proud history in Europe and now it's up to us to live up to the club's name.
"I would rather do that against a top quality team like Toulouse than opposition where we are expected to win by a mile. No one will give us a chance against the champions but it's an exciting challenge."
Cardiff prop Gethin Jenkins will know all about their opponents having lifted the Heineken Cup with Toulon in May before returning to the Arms Park in the summer.
Toulon won 22-14 in Cardiff on their way to winning that trophy and kicked-off the defence of their title with an impressive 51-28 victory over Glasgow Warriors.
Cardiff's Josh Navidi made more tackles (19)than any other player on the opening weekend of the Heineken Cup and is set for another busy afternoon. Maxime Mermoz and Matt Giteau both crossed twice against Glasgow while Delon Armitage and Chris Masoe ensured maximum points for the French club.
- These sides met in the pool stage last year with Toulon picking up wins in both clashes.
- Cardiff's Josh Navidi was the top tackler in Round 1 of this season's Heineken Cup, making 19 tackles in total.
- Cardiff have a win rate of 39% against French clubs - their poorest rate against any nation (P38 W15 D1 L22).
- Toulon have won five of their seven matches outside of France in the Heineken Cup (including the 2013 final at the Aviva Stadium).
