I, too, freeze bananas that are too ripe to eat. When I have enough, I make about a half dozen loaves of banana bread. The bananas, when thawed, are just the right texture to mix up for the bread. I also freeze sweet potato casserole. I make double quantity at our Thanksgiving in October. I serve one pot full with Thanksgiving turkey and freeze the second one for Christmas. I also freeze raspberries but they have to be frozen first flat on a lined cookie sheet and, once frozen solid, can be put into a container together. I have tried freezing rhoti or dahl pouri - these are the big crepe-like coverings for curry and rhoti - but they don't freeze well. They tend to dry out.
