While it is true that certain plant-based proteins lack complete or balanced amino acid profiles, this isn't really an issue unless you are taking in a very larger proportion of your overall protein from one or two plant sources. Each plant protein has a different amino acid profile that has it's own strengths and deficiencies. If you are consuming a variety of starches and plant-based foods, then things balance themselves out and it's not really worth the extra effort to try to micro-manage all of that. As Davinci said, those calories still count, complete protein or not. Your best bet is to count those sources towards your total but make sure that the majority of your protein intake comes from meat, eggs, and dairy.
Quinoa is a complete protein, BTW.
