So my experiment with "pineapple rice bake" is almost ready. It's among the recipes I got when playing with the USDA recipe finder. That site gives not only the how-to but the approximate cost per serving and per recipe, AND the nutritional content, served up in one of the form of those "Nutritional Facts" labels like you see on packaged foods.

I'm making only 3/4 of the recipe (give or take). We'll see if I adjusted everything correctly. I'm using brown rice, too.
USDA estimated cost
Per Recipe: $ 1.95
Per Serving: $ 0.32
