The topic is interesting but also difficult to answer because:
1) You have not specified your gender!
2) You have not told the budget per head.
3) You have not told the location of your school.
4) You have not told your age!
In my opinion, you can actually invite your female teacher having a dinner in one Chinese restaurant in this summer vacation that the cost can be controlled and the environment will not be so silent ( crowded people ). Also the venue will be safety and easy to reach.
Else, see if any classmate has a large apartment who can lend for BBQ and gathering use. If that is the case, the atmosphere will be even better.
Hope I can help you.
