What are the best beans and grains to use to make a good protein mix?

What ratios do I need?

Thanks!
Update: Beardog, now you know I'm asking this mostly about my birds, right? Peanut butter is terrible for parrots, so that's a no-go.

I, on the other hand, love PB and honey on toast.... it's like a Mary Jane.

Of course, I need to get more protein into my diet, so......
