What can I do with, and in the meantime, can I freeze, orange rind?
I freeze lemon, orange, lime & grapefruit zest and rind all the time. You can just pop it in a ziplock if you plan to use it in short order or, sometimes I pour olive oil in the bag to cover and preserve it longer. The oil is infused w the flavour and can be used for the savoury preparations rasputina suggests in addition to stir-fries, marinades, stews, roasts etc. Orange is often called for in Mediterranean and Middle Eastern dishes and of course, Asian dishes.
