Thanks Kristine... Wow she (Maria Emmeritch) is awesome!
You can download her recipe index Excel spreadsheet which you can then search within for recipes based on your macro requirements (includins P:E Ratio).

Also by looking at the calculations you can see how a P:E Ratio is determined with a mathematical formula:
PE Ratio Calculation:
Protein/(Fat+Carbs-Fiber)

Laymans Terms:
Protein divided by Fat+Carbs-Fiber

This appears to be the same calculation that Dr Naimen's calculator uses.

It's my understanding that a P:E ratio of 1.0 or higher is considered a relatively high protein density.

Probably easier to use the web based calculator instead of building a spreadsheet but at least this explains how the formula works.
I love the super easy trick of adding a 0 to the the protein % and comparing against total calories to see if it is less or equal. This still seems to be the best/easiest method when creating or searching for a recipe.
