I had mine with an orange and my usual carrot, but that’s just an example.
Milk.
A second PBJ
I like putting half a cut-up banana in mine, then eating the other banana half for dessert.
BBQ potato chips
Somebody to share it with
I use extra crunchy peanut butter. And make it a little volcano shape on one piece of bread. Then in the hollowed out middle I put a pitt of strawberry jelly.
Then take one more spoonfull and lightly glaze the rest of the peanut butter in a layer of jelly.
If you make the pitt too big, it squirts on your chest.
