Prepare an easy and convenient dinner using the NuWave Oven Pro Plus with Extender Ring Kit. It takes advantage of Triple Combo Cooking Power to cook foods quickly and thoroughly. The NuWave Pro Plus uses conduction heat, just like a conventional oven, convection heat, which circulates hot air around the food and infrared heat, which penetrates food, cooking on the outside and inside at the same time. It also allows you to bake, broil, barbecue, roast, grill, steam, dehydrate and air-fry all in a single convenient appliance that also uses less energy.
