Here is my current menu for my cut. I am aiming to lose approx 14lbs, would this menu, coupled with a 6-day 50-50 split of cardio/weights, be sufficient in helping me achieve my goal?

============

Breakfast - 7.30/8.00am - 2 cups of oats + skimmed milk, a banana

Mid-morning - 10.00/10.30am - Small can of tuna x 1, granola bar x 1

Lunch - 12.30/1.00pm - Wholemeal turkey salad sandwich and an apple or banana

Mid-afternoon/pre-workout - 4.00/5.00pm - This space is as yet empty, this evening I had 3 slices of lean roast beef, mashed potatoes, 1 cup of carrots and 1 cup of cabbage - maybe a baked potato + tuna could go here also?

Dinner/post-workout - 8.00/9.00pm - (When I get hold of the stuff, a whey protein shake will go here as well), chicken breast x 1, 1/2 cup of green vegetables

Bedtime - 11.00pm - This space is also empty, isn't protein the best thing to go here because of the amount of time between meals?

===========

Of course, there is at least 2 litres of water in this menu as well that is consumed while I am on the way to University, while I am there, during my workouts and pretty much at all other times.

The main things I need help with I think are the pre-workout and bedtime meals. If you think it needs slight adjustment or a complete overhaul, please do not hesistate to point out where my weaknesses lie. Please remember I am on a cut and I need to be taking in approx 2100 calories a day (split into 1155(P)/735(C)/210(F) ), so if these amounts are too much/little or if they are the wrong foods completely, please point me in the correct direction :)
