In medium skillet, heat olive oil over medium-high heat.
Add diced onion, and cook until translucent and soft, about 5-7 minutes.
Add garlic, and cook another minute.
Deglaze the pan with the wine, stirring continuously, and cooking until slightly reduced. This took me about 2 minutes.
Add herbs and crushed tomatoes, stirring well to combine.
Season with salt and pepper.
Reduce heat to medium low and let sauce simmer for 15 minutes, stirring often to prevent bottom from burning.
Preheat oven to 375 degrees F.
In 9x9" baking dish, add marinara.
Cut goat cheese into ~½" slices and place on top of marinara, spacing evenly.
Bake in preheated oven for 20 minutes.
Finally, turn on broiler and broil for 1-2 minutes, watching carefully, until goat cheese is golden brown.
Serve with slices of toasted baguette.
