LOL! That depends on what you consider 'unusual'. My DD just recieved Mary Jane Butters Farm Girl book for her birthday ... jello salades are pretty 'unusuals' in Northern California. The DH is from Ohio so he rattled off all sorts of jello salades for her. She said 'weird' and I reminded her that is normal faire in the Midwest and to please call it 'exotic' until she tries some to keep an open mind (we did a can peach and mini marshmallow salade for her to try and she was delighted).
About the only type of mixes we do is when we are packing/camping and they are dried fruits and nuts or homemade dried soup/noodle mixes (I would try the Backpacker dot com for a recipe, most the time I just 'eye' it). We make jerky: beef, venison, tofu but it never reconstitutes up in a soup real well. Nothing too exotic or unusual by us. I guess you could also go to a backpacking shop and look at some of their freeze dried meals and experiment with creating something similar.

Ruthie - internet surfing isn't my best thing. I've googled dry mixes, mix recipes, and a couple of others, but found nothing. Do you know of any one in particular that is good?

My mother has a cookbook called "Make a Mix". I did a Google search for "Make a Mix" and got lots of results. Give that one a try and see if there is anything you like.

Good luck.
