Melt the butter in a microwave-safe dish, then mix in all other ingredients. Get a new microwave safe bowl and coat it with oil. Then pour in the batter.
Microwave for about 2 minutes - you want the top to become firm. Voila! You're done.
The top and the edges (against the bowl) become the "crust" - it's only a little thicker and a little darker in color, but you can control how much crust you have by choosing your shape to have more or less "edge". You can use a large saucer to create a "flat" bread with a lot of crust surface, or a regular soup bowl to have more "insides" that are soft.
To make breadcrumbs, simply crumble into pieces and brown in the oven
