Resort food courts usually have a nice variety. For instance, POP has a make-your-own yogurt parfait, biscuits&gravy side, sausage or bacon, breakfast potatoes, oatmeal, fruit cup, and a smoothie all for a snack credit. Not all are a good use, though.
Savory options in parks are harder to find. QS in France has some. Starbucks locations have bagels and cream cheese. You just have to look over the menus.
