Have you counted your calories?
Have you worked out how many calories someone your height and weight and doing on no exercise needs to eat to maintain the same weight?
Once you've got that worked out, compare that to what you are eating? For objectivity sake, count a menu plan from a past day so that you can't adjust your intake subconsciously.
Whatever number you come up with, if its over 1200, then you should cut back a bit. If its under 1200 then you should increase it perhaps by 100 calories.
For comparison, i'm currently about 165 pounds and am eating about 1650 and no exercise and my weight is stable. I used the calculator in My fitness pal.
if you are not in the mood for exercise, don't add it into the equation. Get your food and calories right first. I also do not give much credibility to exercise calculators for burning calories. I just ignore them.
If you want to reduce some calories form what you are eating, instead of bottle dressing, make your own with 1 tsp extra virgin olive oil and 1 tsp balsamic vinegar. You don't really need 2tbsp of dressing on a salad.
If you are still hungry add more veggies like grated carrot or beetroot into your salad and /or chopped fresh tomato, cucumber, capsicum and things like that. they have practically zero calories but fill you up and make your food more enjoyable.
I put a few walnuts (5 halves) in my salads but i don't eat meat. They make a big difference to the taste.
Cheese is also high fat. You seem to have plenty of protein but you could have a boiled egg for an afternoon snack instead of the cheese. And if you've still calories left, an apple or pear or something like that.
