U didnt tell which sicilian u play...
Schveninguen like i guess.
If u want to avoid white attacking, u can choose accelerated dragon, simple to play and to understand.
At least more than Najdorf and other creatures...
Bobby Fischer on the dragon "h4 h5 sac sac mate"
It doesn't work against accelerated Dragon.
About Maroczi bind mentioned by Pfren, sure it is not simple, but once again if u compare with other sicilians...
But in my opinion, sicilian is a bad choice for "low level" players, really difficult to handle and less educational than 1.e4 e5 or 1.e4 e6.
It's really typical opening
