That sounds lovely, I love the aluminum pouch because it keeps the fish super juicy.
For potatoes, I peel them and dice them, put them in a bowl ad quite a bit of olive oil, salt, pepper and smoked paprika and a few cloves of garlic (unpeeled). Mix everything and to the air fryer they go. I love the garlic touch, adds a lot of aroma to the whole thing.
I think I'm behind the times as I don't have an air fryer yet :D
