Is getting 30% of protein from incomplete sources okay?

I have around 8 slices of bread, I'm trying to bulk up and also build muscle.

I'm 5'6 and around 59KG, and my protein goals are around 95G-120G.

Around 30G comes from bread, because I have 4 slices for breakfast (with egg) and 4 for lunch (with some kind of filler). It's easy and convenient for me because it gives protein, tastes nice and manageable.

I have a feeling that maybe I eat too much bread? I'm an anxious person and around 30G out of the 100G protein I have comes from incomplete sources. Is this okay?
