im on a cutting diet

and my lunches would be something like

Pasta, traditional ragu sauce and cottage cheese
( any opinions on what type of sauce to use for pasta, any healther ones?)

tuna fish about 4 days a week

and i was eating turkey sub sandwhiches with some mustard until i was told on these forums that bread and cutting isnt the best idea ..

i need opinions on my sauce for pasta, on bread for turkey sub sandwich and more ideas for lunches because its where i seem to struggle the most on my cutting diet
