Hi E., Love your website. My 2 little guys have the celiac gene, but have never had gluten in their diet. My husband (AKA taste tester) is celiac, as are most of his relatives, so we have a Gf household.
Have you discovered the Food for Life brown rice tortillas? They make great sandwich wraps and quesadillas. I will sometimes use one of these quesadillas as the base of a quick pizza. The boys love them. If you are using them as a wrap, nuke them a few seconds with a moist towel to give them a little more flexibility.
They also like cold cut roll ups(roll up cheese and veggies inside 2 cold cuts)they can dip into a sauce.
I have tried lots o' bread mixes and find that Pamela's makes a wonderful sandwich bread that doesn't break up like lots of GF bread does. I add flax meal and molasses and even protein powder to pump up the nutrition a bit. SOOOOOO much better than some of the crumbly store bought GF stuff out there.
I also make a fruit and veggie bread (using the basic banana bread recipe on the Bob's Red Mill GF All Purpose flour bag). I sub a rough puree of whatever veggie/fruits I have (zucchini, sweet potato, banana, raisins, carrots, dried cherries...you get the picture) for the banana amount, add flax meal, molassses, nuts, and use agave. It pretty much flies out of the kitchen.
Happy Lunching, Songbird
