Hi J Lin T
Were gf as well. So far I've packed a cheese sandwich on some brown rice bread, I found it's cheepest at Trader Joes 3.something, as to the 6.00 other stores. I toast it a little before makeing it.
I sent rice crisps and cheese cut w/ mini cooke cutters and friut yesterday like a lunchable sort of thing. And was also thinking humus w/ corn chips. We have also used gf pancakes to make sily sandwiches. What about sunbutter ants on a log? Apples and dip mix some sunbutter, or almond butter w/ agave and cream cheese to taste and eat w/ apples. A little lemon or orange juice on the apple slices will help them not brown, but it changes the feel to the fingers. Don't know how much your picky eatter is like mine.
Best of luck to us! A. H
