Step 1

Combine red and yellow tomatoes with salt in a large bowl. Let stand, stirring occasionally, until the tomatoes soften and release their juices, about 40 minutes.

Step 2

Bring a large pot of water to a boil over high heat. Add pasta and cook according to package directions. Drain and rinse with cold water.

Step 3

Dry the pot and add oil; heat over medium heat. Add shallots and garlic; cook, stirring occasionally, until the shallots soften, 3 to 4 minutes. Add crushed tomatoes and their juice; bring to a simmer. Cook for 5 minutes. Add the pasta, the fresh tomatoes, chiles, arugula, oregano, crushed red pepper and ground pepper. Cook, stirring, until hot, about 2 minutes. Serve topped with Parmesan, if desired.
