Recover deleted data SQL Server
Any suggestion on how to do that?


The Easiest way to recover the data (in your scenario) using third party tool
which help you to read transaction log (backups or online),  and able to generate (T-SQL) script that can recover particular data effected by delete operation. 

In case if the recovery model is simple, database has to be set OFFLINE or detached for making live database files connection to do the recovery, since the LOG Backup cannot be possible in simple recovery mode. However, Chances are less (in simple recovery) if the duration between recovery action and deleted operation is too long as the log truncation happens automatically.
