Would this subway sandwhich be considered healthy?

Foot long, whole wheat bread, chicken teryaki, lettuce, spinach, cheddar, tomato, ranch (small amount), and avocado. I want a sandwhich that I can eat at least 3-4 times a week because I have no time to make anything I`m honestly ALWAYS busy. Basically I need a sandwhich that will keep me healthy and not make me gain weight.
