Seeking sources for protein that are not eggs or poultry ( trying to mix it up) no Tofu. Thinking of a low glcyemic load... perhaps a bean?

Thanks.

I am trying to have a few meals that are not heavy on the protein via poultry or eggs.

I was thinking about looking at the lowest glycemic bean match.

I am using chickpeas on salads

Breakfast is the mountain I must climb.

I have done things like stir fry for breakfast or soup but the protein seems to stay the same with chicken, turkey, eggs.  Tofu and soy products wouldn't work.

I use protein powders on occasion.  Mostly plant based but yuck on one level and stevia on the other.

Any ideas?  Thanks!
