Legume proteins

Legumes are a staple in my country and I read online that sprouting moong dal or mung beans increases protein digestibility and bio availability like 85% ? So 100g raw moong dal will give me 20g protein ? Of course its incomplete to I will day with rice not on the same meal but throughout the day , so I was also wondering if I can grind those and ferment them to make moong Chile to get Max protein digestion ? And it reduces excess water so maybe I can eat 150g raw moong dal in the entire day for 30g protein ? I just read stuff online and not a expert , this just my hypothesis which can be wrong but I would like to know since moong dal is available everywhere and affordable.
