It's so wet that it will develop big ice crystals. If you make pizza fairly often, I think it would be ok, maybe? I'd try it anyway! I'd slice it up, freeze it on wax paper on a sheet pan and then put in a ziploc. It use a vacuum sealer if you have one.
If you want to use it, toss it on any salad. Though this time of year beets & pistachio would be good or citrus with avocado. You could also use it on a sandwich (hot or cold) or drizzle a little olive oil & balsamic and eat it with some good toasted bread rubbed with a garlic clove.
