Done this in an fully certified for UPRT A320 NEO Sim:
As a stall is only dependent of AoA first and most important thing is to lower pitch. Well below the horizon. Then roll wings level, check speed brakes retracted, because these reduce your critical AoA. Thereafter deploy FLPAS 1, as they significantly increase your AoA crit. If you see a good positive speed trend add a little bit power and when slats are half way out and speed is above Vls start releasing the forward stick input to smoothly let the nose rise. If terrain is no factor, altitude loss is secondary. It will be approximately 4000'.
