You can find a "basic soy grits" as well as a couple of other recipes at https://www.bobsredmill.com/recipe/.

Just select "soy grits" from the drop down menu and it will pull up all the recipes for that ingredient.

You can buy it online there, but large grocery store chains usually have a gourmet/organic section that carries at least some of the Bob's Red Mill products. If not, try health food/organic food stores.

There are also a couple of recipes at Sherrie's site:
