There are gluten free lasagna noodles, so I would make a pan of lasagna to take, unless the person/people can't have dairy either. I would find that out, of course. But if dairy isn't a problem, you can omit the meat/hamburger in traditional lasagna and just add a lot of veggies (spinach, zucchini, summer squash, carrots, etc.). Gluten free lasagna noodles are, of course, more expensive than regular but they cook just the same. You can get them at health food stores, some grocery stores like Meijer too. There are many other gluten free pastas too, so you could make just about any kind of pasta dish with those.
There are a lot of cooking/recipe web sites, many of those have a lot of good gluten free recipes as well.
