Perennial sources of lysine?

I’ve been messing around with hypothetical food forest diets on cronometer.com. Cronometer is a useful website because, unlike other nutrition trackers, it breaks “protein” down into its constituent essential amino acids usind USDA and NCCDB data.

With sunchoke, chestnuts, hazelnuts, collards (stand in for perennial brassica), and prunes (stand in for assorted preserved fruits) we can hit the target for just about every nutrient except lysine. In my domesticated diet, I get more than enough lysine just eating beans. Unfortunately, there do not seem to be any practical perennial bean crops (yet!), though perhaps someone will one day make one using lupines, thicket beans, siberian pea shrubs, etc.

Are there any alternative sources of perennial lysine that you can think of? I guess I could always grow more nuts, which have a fair amount, but it would be nice to diversify a bit more.

Also regarding the cronometer images, don’t be overly concerned about the red manganese stat – supposedly manganese toxicity has not been observed from dietary sources.
Also disregard the lack of carbohydrates; another question for another time. I’m experimenting with american groundnut, but I could not find nutritional information for this tuber. Sunchokes are yummy but not very caloric – you would need to eat like 6 lbs a day to stay alive
