Toast the bread in a toaster and while it is still warm, spread the fig spread on each slice to cover it entirely. Place the cheese in a bowl and heat in the microwave for 30 to 45 seconds, until it's creamy and spreadable. Spread a layer of the cheese on the fig spread, leaving the edges of the fig spread visible. Sprinkle lightly with salt and pepper. Cut each toast crosswise to make appetizers that will be easy to eat. Place a fig slice on each piece, top with a few microgreens, and drizzle lightly with the balsamic vinegar. Serve at room temperature.
I prefer fig spread, which has less sugar than fig jam or fig preserves, but of course you can use either. Choose a fig spread that is quite thick or it will be hard to spread the goat cheese on top.
