Well, I think a lot of stuff isn't too horrible if you eat small portions, and I always try to choose something with natural ingredients rather than lots of chemicals.
As far as healthy though, I think the neat witches brooms made from pretzel sticks & string cheese are cute (search on pinterest for photos & how to), and I make a delicious pumpkin dip that's not bad. You take a can of pure pumpkin, add a block of *softened* cream cheese (you could do the lower fat kind), and a tub of cool whip (you could do the lower fat kind or even skip this ingredient), then add powdered sugar, nutmeg, ginger or pumpkin pie spice to taste.
You can dip apple slices, ginger snaps, large marshmallows, graham cracker sticks, lots of things. Stick with the apple slices to be healthy though. This recipe makes a lot, so I normally make it for parties & serve it in a hollowed out pumpkin. You can put leftovers in the fridge.
Many pumpkin muffins, pumpkin bread or the like are probably pretty healthy for you if you make it from scratch. I always substitute coconut oil for any oil in recipes, but when I make banana bread, I use applesauce in place of the oil & it's awesome! A pumpkin bread with nuts, raisins & applesauce instead of oil would be really yummy!
