I have the 5 in 1 Ninja Foodi Grill, and so far, I totally love it. (Okay, I unpacked it Monday, used it Monday and Wednesday). I made hamburgers (black bean for me) on Monday. I put a probe in the burger, set it for medium rare, and pushed button, then, I went and watched the news, a little bit later, the machine beeped, and everything was perfectly cooked. Fantastic! Zero smoke!
Okay. It doesn't taste like a charcoal grilled burger, but considering all I had to do was put food in, and press a button, that was pretty great.
I liked the fajitas last night, I used no oil, steak, onions, peppers, Tajin, same thing, put food in, pressed a button, went and took a shower, then, magically, 20 minutes later, the food was perfectly done. I love this thing. I am doing shrimp tomorrow.
