subway sandwich

[onlinebeginner]

I just started working out regularly (3 days a week) a couple months ago... nothing crazy and i drink a protein shake during as well as after

just trying to eat healthier in general to be healthier, feel better and look better

Subway Footlong sandwich
Whole weat bread
Chicken breast
(no cheese sometimes...testing out if i notice taste difference)
Light onions
tomatos
lettuce
mayo
oil
just a little ranch


I usually eat the first 6 inches.... then wait 2-4 hours (depending on my hunger/activities) and then eat the other half

i feel like this is a fairly healthy option... but am i correct?

gimme some advice how I can improve this
