Preheat oven to 375 degrees. Place the two rounds of Boursin cheese and tomatoes into a 9 x 13 baking dish. Drizzle with olive oil, a generous amount of salt and pepper, garlic, and red pepper flakes.
Bake in the oven for 30-35 minutes.
While baking, heat water in a large pot to boiling. Generously salt the water. Add your favorite type of pasta and cook according to package instructions. Remove ½ cup of water and set aside to add to sauce. Drain the pasta.
Once the tomatoes are done roasting, toss with cooked pasta and reserved ½ cup of pasta water. Sprinkle with fresh basil, spinach (if using), and parmesan cheese.
