How's about strength training???? The more muscle we've got the more calories we burn. It is the only known proven thing to increase the rate at which we burn calories. So if you haven't added in that yet, I'd say it's definitely time!!! A simple resistance band is all that's needed. You can google resistance band workouts and a few good ones will come up.
And I am a firm believer if you want to create MORE of a calorie deficit, that ADDING in calories to your day is NOT the way to go. I'd much sooner decrease those calories then raise them, so yes I'd definitely eat less, not more, especially if you're stuffed.
Another thing - I'm not seeing much in the way of veggies in your menu - let your foods work for you. Get rid of those granola bars (glorified candy bars IMO) and applesauce (no real value there). Go with the veggies, veggies, veggies and some fresh
Kick it up a notch!! Tweak those foods, tweak that exercise - watch that scale go downward once again.
