I used to find my first one very useful when unwell - I could cook a whole meal in it, stacked up in separate containers, but I cannot remember just what! I would prepare everything in one spell of being capable, and eat it in the next.
I have also used a very small one for breakfasts. It was stupidly small, I thought when I saw it in the shop, about the size for baking one apple. But when I thought of breakfast I got one in the sale. Just right for porage, but also able to cook bacon and sausage and tomato. Or something I got off a Texan site, without the chilli, potatoes and other breakfasty stuff, with a beaten egg. Some of those needed much less time, so I used a timer. I was doing breakfast in my bedroom at the time so as not to disturb the couple downstairs under my kitchen.
The company now sells that size for chocolate fondue.
