I like this site and have two of her Instant Pot cookbooks.

Easy, healthy, and nourishing are all relative terms, OP.
I have tons of cookbooks, and I often modify recipes to have less salt and more fiber, and tend to avoid baked goods because I tend to avoid wheat and sugar — my personal version of healthy and nourishing.
Love and lemons is another site that I like — and there’s a cookbook with the same name.
