The toaster oven that I use is Tovala as part of a prepared meal service... and they're fairly good. It uses QR codes on a recipe sheet to set up a sequence of events for the toaster oven. That is, if you scan the "chicken and bacon ranch Swiss melt" it will bake at 400°F for 15 minutes, steam at 425°F for 3 minutes, and then broil for 2 minutes. It can also do some groceries from the barcodes on there. I was pleased to find that the corn dogs that I occasionally got had a pre-programed recipe as do the single French bread pizzas. When its all done, the toaster oven beeps and I get a haptic feedback on my iWatch. It does have buttons and display for a regular sighted person too - its not a slave to the app and barcodes. I'll note that I don't know how the iPhone app fares for accessibility. However, I do know that someone could set up index cards with barcodes (QR or regular) on them and have it either run from its (limited) set of store bought grocery meals or run a recipe sequence associated with that barcode in the app. Those index cards could also have braille on them for instructions and identification. With some assistance and initial setup, it would be possible to that toaster oven to be a fairly accessible device for a set of meals (that can be extended with assistance).
