An air fryer, I now use it almost as often as my microwave. It can cook meat, fry potatoes, roast vegetables, reheat frozen meals (for my extra-lazy pizza bite days), toast bread… some leftovers even reheat better in the air fryer than the microwave (eg pizza). I actually just splurged on the DREO ChefMaker Combi Fryer based on an Adam Ragusea recommendation, basically air fryer++ with smart heat cycles, built-in thermometer, and a water container for programmatic steaming.
