Critique my diet + lifestyle

Hi! I am relatively new to all of this (I only really started being serious about losing weight about a month and half ago) and I wanted to see if I am on the right track and where I can improve.

One thing to note is I am interning in a different city, so I am constrained on money/support. Also I am a pollotarian (no red meat).

I am currently 195 lbs (88.4 kg), 5' 9" (175 cm), 20M. My breakfast is usually one egg and one cliff bar. I either do a 5 minute bike or 20 minute walk to work. For lunch, I usually have a chicken salad (440 cal, 51g protein, 19g carbs, 18g fats) or sometimes my work caters sandwiches (I don't really know the macros of it, I assume it's around 800 cals). I usually either bike or walk for 30 minutes during my lunch because I eat fast. Then after work, I incline walk on the treadmill (13 incline, 2.5 speed) and do strength training for 45 min to 1 hr (arms+shoulder, chest+back, legs). And then I bike/walk home (though usually I take a longer route). For dinner, I typically eat some chicken finger salad sandwiches from star market (640 cal, 30g of protein, 70g fat, 15g carbs). I also drink a protein shake which is 120 cal and 24g of protein.

All in all, my TDEE should be around 2200 kcal so I have been trying be under 1700 cal and my Apple Watch says I burn 600 calories (but I know Apple Watches aren't accurate). I think my biggest weakness is low protein, fiber and carbs? Any advice?
