Im in a calorie deficit and idk if its good or not

For breakfast, I eat whole-wheat toast with an egg cooked with a little butter, ham, and a little cheese. For lunch, I eat a lot of cucumber or green salad with oven-baked chicken cutlet (without oil) or air-fried chicken pancakes (without oil), and air-fried potatoes (without oil), but not always.
For dinner, I make another toast like the one I had for breakfast, or an omelet, or I eat nothing.
I just stared my deficit and its so hard for me to stay consistent like i always start and never finish so im really trying this time to stay consistent. I do eat random things sometimes like today i had 2 slices of pizza for dinner and I do feel guilty but it it what it is.
Anyway I wanna get opinions about my deficit
