Any non-gebrochts Pesach recipe is good. Kasha is great as a side dish, or brown or white rice. I have recently acquired the taste for quinoa also. Apple kugel or pineapple kugel, made with potato starch, makes a nice side dish.
One of my close relatives has celiac, and she is compeltely gluten free. There are rice noodles that taste virtually identical to wheat, and make great luckshen kugels. Eggplant parmigiana is a great dfish also, as is any fish, meat, or chicken, made without matzah meal or bread crumbs.
