jerky, apples, bananas, peaches, pears, kiwi, and cantaloupe and plums are my boys' favorites. For me, berries work best in fruit leathers (too much work though for the amount I get), frozen, or ground up into a powder after dried. I use a handheld coffee grinder, well-cleaned.
Sweet potatoes baked, and smashed are surprisingly delicious.
Congrats on an amazing score! I love mine!!!
