Quick question. Can/how best can I freeze aubergine?

[acrabadabra]

Bought yesterday with intention of making a vague moussaka but didn't have time. Going on holiday tomorrow and can't use it with tonights dinner.

Will it freeze and if so, should I slice it and grill it first. Or will I have to just bin it. Want a quick fix if possible.

TIA

I would normally make it into aubergine parmesan before freezing but according to this you can slice and freeze:

Freeze slices of eggplant to use in eggplant parmesan and other dishes. Slice eggplant 1/3-inch thick and blanch for 4 minutes in 1 gallon of water with 1/2 cup of lemon juice. Cool, drain, and freeze in an airtight bag or container with 1/2-inch headspace.
