For soft pretzels we use the alton brown recipe. We make them for a yearly event. So I have to make them a few days ahead of time. They turn out great. At the even we eat them cold, but at home we microwave them for a warm treat. They don't get soggy or anything. http://www.foodnetwork.com/recipes/alton-brown/homemade-s...
My husband was on a low residue diet for most of the summer. He had many of the same restrictions, but he also couldn't tolerate dairy. Some things we came up with were mini chicken sandwiches...often chicken salad, but sometimes bbq (we made a not too spicy version ourselves).
Tortilla rolls ups. We just kind of filled them up with things he could tolerate.
Avacados are low residue...so we made a mild guacamole. Totrilla chips were a bit high in fiber, but pita chips were ok.
And since hummas was pureed, he ate that a lot.
There are also many recipes for tasty mini quiches that will meet your needs. We brought those for a BBQ once and they were a big hit.
