• In a small microwave-safe bowl or ramekin (mine measures 3 inches on the bottom and 3.5 inches at the top), melt the butter in the microwave.
• Allow the melted butter to slightly cool, then mix in the remaining ingredients until smooth.
• Microwave the mixture on high for 90 seconds. The bread will puff up while "baking," then slightly deflate. When done, it will look like a muffin. Make sure it appears set, otherwise microwave it for 10-20 more seconds (but 90 seconds should be enough, and overcooking can dry it). Take care when removing it from the microwave. The bowl will be hot. 
• Let the bread slightly cool, a minute or so. Then gently, with a paring knife, loosen the edges and remove the bread from the bowl onto a plate.
• Slice the bread crosswise into two slices and top it with your favorite toppings.

To toast the bread:

• Heat a pat of butter in a medium skillet over medium-low (not higher) heat. Or spray the skillet with olive oil spray.
• Add the bread slices. Cook, gently pressing on them with a spatula to ensure even toasting, until golden, about 3 minutes per side.
