This might already be available but I was thinking about the other day.
I know you can use frozen fruits and veggies..

Can you puree the fruits and veggies and mix them into the staple, and then freeze all of it together?

It would be difficult to keep the proportions right. Blending the fruits and vegetables reduces their volume so it is difficult to determine exactly how much is equal to 1 TBS of cut up fruit or vegetable.

I do not think any blender will hold the equivalent of a batch of HPW plus equal amounts of fruits and vegetables to go with it.

Once mixed and blended you would not be able to tell how much to offer each glider nightly to ensure they get about 1 TBS HPW, 1 TBS fruit and 1 TBS vegetables.

Gliders also like to be able to pick up fruits and vegetables to munch on them. They do not need all of their food blended.

That makes a lot of sense. I was just curious! Thanks Candy. =)
