I use the jar sauce as well for a lot of stuff…first I brown lots of garlic in olive oil and add spices like Italian Seasoning, salt/pepper, and fresh parsley, it’s pretty good for a quick sauce,Left over canned sauce isn't a problem. I use Classico sauces with the screw top. I always pour it into a sauce pot and add a pint of homemade medium tomato salsa and use it that way. When finished I use a canning funnel and pour the sauce back into the jar, screw on the lid and put in frig. I can get 2 or 3 more 13" pizzas from one jar that way.
I have an air fryer with a basket similar to that shown in the picture. I think it would almost be an exercise in futility to get those pizzas out with a spatula.No, it would come out ok, but, It would take forever to do the entire can of little pizzas.
The oven would do the entire batch in 10 minutes.
