Yes, it will be possible to find a mini oven with a hot plate, in fact they tend to come in pairs so you will be able to cook your meal in the cavity and use the hot plates for your potatoes, pasta or vegetables. But, take the time looking as many compact ovens don’t feature them. It will, of course, be a personal choice, but for me, when I was buying a table top oven for my sister they were an essential feature (There was a delay in her new cooker arriving and she didn’t have a hob for back up).
