Preheat an oven to 400ºF. Place a large pot of salted water over high heat to boil.
Scatter the tomatoes onto a baking sheet and drizzle with about 2 tablespoons EVOO and some salt and pepper. Toss lightly to coat and roast them in the hot oven until they burst open and are tender, 12-15 minutes.
Place the bacon on a broiler pan and transfer to the oven as well. Cook until crispy, about 15 minutes.
While the tomatoes and bacon are in the oven, drop the pasta in the boiling water and cook to al dente according to package directions. When the pasta is ready, reserve a large mug of the starchy cooking water and then drain the pasta and return it to the pot it was cooked in.
