C.B.
I slice bell peppers so that they look like a ring (complete circle). My girls wear them on their arm like a bracelet and eat it that way. They LOVE bell peppers and request their "bell pepper bracelets." They also like when I grate carrots really fine with the cheese grater and then mix it with raisins/craisins.
I must say my girls LOVE all fruits and vegetables though and we really don't have a hard time with them eating things, but I still like to make it fun for them and present it in interesting ways.
You could disguise spinach in mashed potatoes by just mashing it all up together and baking it in the oven with a little cheese over top.
I have found that my girls prefer their vegetables raw instead of cooked (maybe consistency??) You could try to offer her (raw) carrots sliced up, etc.
