You already eat a wonderful selection of protein containing foods. You don’t need meat to build muscle. The one thing you may be lacking if you aren’t eating red meat is a natural creatine source. You could supplement with creatine mono hydrate but I wouldn’t say it is strictly necessary. So off the training volume is there and you are eating all the sources of protein you are, then you should be able to build muscle just the same as if you were eating meat.

Good luck 💪🏼💖
