If you are talking about whole foods I don’t think there are any non meat sources as dense as meat. If you go processed maybe peanut powder gets close. I’m limited to beans, soybeans and nuts for the most protein. With beans you’re gonna get some carbs and with soybeans you will get some fat too but it is high quality unsaturated so that is ok for me. Nuts come with a lot of fat including some saturated fat but I’m not worried about that because that is my only source of saturated fat now since avocados are gone from stores in the midwest.
