Today, I went with my daughter to the local supermarket with huge kosher sections (including a kosher bakery section which strangely was still filled with regular "chametz" bread and other baked goods being purchased I guess by non-Jews and non-observant Jews). I saw a display with small cookbooks by "kosher.com" that said "free: take one", so we did, and we found that it had quite a few recipes that sounded quite good. Then I saw a link, possibly posted by a FaceBook friend to the kosher.com website and I found that it has literally over a thousand Passover recipes! Many of them seem quite simple and do not require hard-to-find food items, although some of them some of them sound difficult (one recipe for making a fruit sorbet even tells you how to get rid of the sugar that got over cooked by a mere 10 degrees since the recipe only works if the sugar gets to between 240-250 degrees, but not hotter!) and some do require items like coconut flour or walnut oil which might be hard to find. But I made copies of many of the recipes to use for the future and wanted to share this amazing resource: Kosher.com Passover Recipes
Note that you can filter the recipes for included or excluded ingredients which could be helpful for those with special dietary restrictions. I chose Diet=vegan and Holidays=Passover, and there were still hundreds of recipes listed.
I'll have to check out the other recipes that the website has for other holidays as well.
