I have a friend who just loves her air fryer. She has a rare medical condition and her medications give her a very restricted diet. One of her few joys of allowed foods was french fries, but when she had her gall bladder taken out, she just couldn't tolerate any fat at all. Tada, enter air fryer. As she says, iced tea and french fries may not sound like a banquet, but even less so without the fries.
She has a large family sized unit but is very happy when she makes a single serving. Well... maybe on my low carb diet more than a single serving, but less than a party of five!
