For this dish, how big is the pizza sauce jar - could only find pizza topper in Tesco which was 200g

Looks lovely my kinda food but the potatoes were hard. Might put them in the microwave first if I cook again. Cx💕💕

I couldn’t find pizza sauce in a jar. Would pasta sauce work ok? Thinking I might just water it down a little bit?

Do you need to par-boil the potatoes before putting them in air fryer? Is 20 mins long enough so the potatoes aren’t hard in the middle?

Is this 4 portions?
