I personally consume 2.4 L of raw milk yogurt (although I wouldn't advise anyone about the raw part unless you know you're getting the milk from a trusted farmer and you have a good enough immune system to handle possible pathogens in raw milk) which gives me about 70-80 grams of protein. I also consume 300 grams of whole wheat flour fermented using sourdough culture which gives me about 40 grams of protein. Both of these are high quality, highly bioavailable protein sources (the sourdough fermentation breaks down any anti-nutrients in the flour such as gluten and oxalates). In addition, I also consume plenty of fruits which gives me about 5-10 grams of protein. Coincidentally, this also covers almost all the micros too.
All in all, I'm quite easily able to get about 120 grams of protein and almost all the micros I need from this kind of a vegetarian diet. So diet-wise, there's certainly no restraint from not eating meat/eggs as regards to getting enough protein as well as your micros. Which in turn means that there shouldn't be any restraint in being able to build muscle when such a diet is combined with a bodybuilding routine.
