Preheat oven to 375F.
In a medium pan, heat olive oil over medium-high heat. Add garlic, basil, oregano, salt and red pepper flakes. Saute for 45 seconds or until garlic is fragrant but not browned. Stir in the tomatoes and heat at a gentle simmer for 10 to 15 minutes, until the sauce starts to thicken. Remove from the heat.
Pour the tomato mixture into an oven-proof baking dish, top with sliced goat cheese. Bake for 15 minutes, broil on high for 4-6 minutes, watching carefully, until the goat cheese is golden brown.
To make crostini, slice baguette and toast at 375F for 15 minutes.
