Preheat the oven to 420°.
In a medium baking dish, arrange the tomatoes and garlic around the goat cheese log in the center.
Brush the harissa paste on top of the goat cheese log.
Drizzle the olive oil on top to coat, and finish with the dried herbs and a healthy pinch of salt and pepper.
Once the oven is done preheating, place the baking dish inside and cook for 25-30 minutes or until the goat cheese has browned and tomatoes have burst open.
When finished, remove from oven and let sit for 1 minute.
Add the balsamic vinegar and mix everything in the baking dish together.
Add the spinach and warmed quinoa, toss to coat, or until the spinach has started to wilt.
Season with salt and pepper to taste.
Place into bowls and garnish with fresh basil, if using.
Enjoy immediately.
